==Explanation==

[[Randall]] is again promoting his new book, ''[https://xkcd.com/what-if-2/ What If? 2]'', and starts by explaining the kind of recipient who might appreciate it, basically anyone who is into science or anything in the universe... So basically anyone.

Then he also gives both direct and humorously indirect instructions of how to obtain the book for them, the latter method making a jocular (but not completely wrong) presumption that almost any text-input widget leads to some relevant search-engine result. Also the entire comic is a link to the ''What If? 2'' page on xkcd that's included in the comic. As always, clicking anywhere on the image will take you there (including actually clicking on the link).

He also suggests some other tongue-in-cheek gift ideas for several other subtypes of gift-receiver, most of which are, in keeping with the ''What If'' ethos, somewhat dangerous or impractical. A number directly reference things previously mentioned or depicted by xkcd.

! Interest !! Gift Idea !! Explanation
|-
| Engineering || The {{w|International Prototype of the Kilogram|platinum cylinder}} formerly used to define the kilogram || This is an object of historical relevance of which only six exist, making it a very expensive or illegal gift. With the {{w|2019 redefinition of the SI base units|redefinition of the SI base units}} in 2019, {{w|2019_redefinition_of_the_SI_base_units#Kilogram|the kilogram}} is now defined using only natural constants rather than a physical standard. It took some time before this last SI unit was redefined, 3 years prior to this comic's release. The old prototypes are no longer as important as they were when they were actually used to define the kilogram. But they are still historical artifacts with enormous value, even apart from the value of a  kilogram of platinum (about $32 000 at time of writing).
|-
| Biology     || The genomes of the scientists who headed the human genome project || The "International Human Genome Sequencing Consortium," as the {{w|Human Genome Project}} team was known, involved scientists from twenty institutions in six countries. In the US, it was initially led by DNA structure co-discoverer {{w|James Watson}} who was succeeded by {{w|Francis Collins}}. In the UK, the project was led by {{w|John Sulston}}. The teams from other countries' institutions were less prominent and performed substantially less work on the initial sequencing. James Watson's genome was sequenced in 2007. The genome of {{w|Craig Venter}}, the CEO of {{w|Celera Genomics}}, was used as the exemplar for Celera’s sequence. While the “race” between Celera and NIH was declared a tie by then-President Clinton, in actuality, Celera had some 85+% coverage while NIH was about 50%. 
|-
| Physics     || A beam of neutrinos delivered through the earth by the LHC || {{w|Neutrino}}s interact very weakly with other particles, to the point that they almost always pass straight through matter completely unaffected. This means that particle accelerators (such as the {{w|Large Hadron Collider}}, or LHC) can send neutrinos to any other point on Earth by aiming the particle beam into the ground, and the neutrinos pass straight through the Earth. This point is referenced in the What-If article "{{what if|73|Lethal Neutrinos}}". The low interactivity of neutrinos would also mean that the recipient would be unable to perceive their gift, making this a poor present for anyone except the small proportion of physics aficionados who already have a neutrino detector on-hand.
|-
| Animals     || Surprise wildlife encounter (gift-wrapped box with a bobcat inside) || This is a reference to [[:Category:Bobcats|xkcd's rich history of mailing boxed bobcats to people]]. This gift would place the recipient in a perilous situation, and, although definitely a wildlife encounter, is not a good gift.{{Citation needed}}
|-
| Law         || A vacation to that area of Idaho where you can commit crimes with impunity due to a court district boundary error || This refers to the "{{w|Zone of Death (Yellowstone)|Zone of Death}}", a 50-square-mile area of Yellowstone National Park that is in the physical boundaries of Idaho, but in the legal jurisdiction of Wyoming. Because a jury in the United States must be composed of residents of the same district ''and'' state in which the crime was committed, but no one lives in this small area of a National Park, anyone who committed a crime here could not (according to a legal theory not fully tested in the courts) receive a trial, and thus could not legally be punished for said crime in any circumstance. This is an interesting legal loophole, but going to this area does not provide any more value than hearing about it, and could scare your law-enthusiast friend.
|-
| Chemistry   || A necklace of element samples whose symbols spell out the recipient's name (note: names like "Katherine" and "Brandon" may cause radiation accidents.) || Novelty necklaces are a common and innocuous gift. The {{w|Periodic Table}} traditionally represents each of the chemical elements with a one or two letter symbol. Using these symbols to replace letters in a name is a common gimmick (famously used in the title and credits of {{w|Breaking Bad}}). Using real samples of the given elements could be difficult, as elements can be expensive, highly reactive, or toxic, and some are gaseous or liquid at room temperature.  Reactivity and toxicity can be dealt with by containing them in well-sealed containers, which would also be necessary for non-solids. Radioactive elements, on the other hand, could be dangerous even if well contained, and some have half-lives too short to make them a practical gift. Spelling "Katherine" entirely with elemental symbols requires using {{W|astatine}} (whose symbol is "At"), and "Brandon" would require {{W|radium}} (with the symbol Ra). Neither of these elements have stable forms, and both would put out dangerous amounts of radiation. If worn as a necklace (and thus constantly near human flesh), even a small sample of either of these would be dangerous. Additionally, the letters J and Q do not appear in the standard periodic table symbols, while M does not appear on its own (only followed by six other characters, with "o" as the only vowel amongst them), so a name like John, Quinn or Mike would be problematic.
|-
| Puzzles     || Two goats and a new car || This is a reference to the "{{w|Monty Hall problem}}", in which a game show contestant has to choose between three doors, two of which conceal goats and one of which conceals a car, and wins whatever prize is revealed. (See [[1282: Monty Hall]], for another cartoon inspired by this problem.) This gift places the recipient within a puzzle which is typically discussed hypothetically rather than happening in real life. Although many people would consider a new car a ''great'' gift, those who would appreciate a gift of goats are less common.
|-
| Technology  || Cybiko® wireless handheld computer for teens (2000) || This is a direct callback to [[2699: Feature Comparison|one of the previous week's comics]], which humourously suggested that this device is a better option than most of the current popular communication technologies. While an interesting example of the history of communication technology and coming from a time when experimentation was common and standards were few, it isn't very useful now, because it is no longer supported, has a communication range of 100 meters (sending text messages via radio) and one can only use it to communicate with users of the same device. However, technology enthusiasts could find it interesting as a collectors' item, so by all means it is one of the most plausible gift ideas on this list.
|-
| Space       || Webb telescope personal photoshoot || The Webb telescope belongs to NASA, the ESA and the CSA, and is currently very far from Earth. It is designed to capture distant space objects in previously unseen detail. If the photoshoot implies photographing a nearby human, it is not designed to do this, even if the difficulties of sending a human about a million miles to its location could be overcome. On the other hand, if it means photographing the recipient on the earth's surface, Webb would have to point at the warm Earth and expose its optics to the Sun, permanently crippling the telescope ([https://webb.nasa.gov/content/about/faqs/faqLite.html Which is forbidden by NASA.]) and it would not have sufficient resolution to make out the subject in any case. These circumstances make it a highly impractical gift, to all intents and purposes to the point of impossibility. 

On the other hand, a gift experience of being allowed to take your own snapshot of Webb in position, perhaps with a [https://www.dailymail.co.uk/sciencetech/article-10442913/James-Webb-Space-Telescope-seen-Earth-settles-orbit.html robotic telescope], might be an attractive gift to a space enthusiast! So might a chance to use the Webb telescope to take pictures of whatever celestial objects one chooses, as time on the Webb telescope is very carefully allocated.
|-
| Literature  || Stephen King's writing desk (he's still using it so you'll have to fight him) || {{w|Stephen King}} is an author lucky enough to have legendary status while still alive. The desk of a famous author who has died would become an object of historic significance and would likely be either kept for exhibition or auctioned by their respective estate, but as Stephen King is still alive, he would probably object to his desk being subjected to the same.
|-
| Philosophy  || Out-of-control trolley || This is another gift that places the recipient in the situations that they like discussing hypothetically. The {{w|trolley problem}} is a thought experiment in which one is asked to decide between allowing a trolley to kill five people or taking an action that causes it to kill one. Presenting someone with such a hypothetical problem may or may not be not a good gift, but [https://www.youtube.com/watch?v=1sl5KJ69qiA forcing them to live through it in real life] is a terrible gift. (See [[1455: Trolley Problem]] for another cartoon inspired by this problem.)
|-
| Psychology  || A nice gift with a note saying you don't expect anything in return || This unkind attempt at psychological manipulation is intended as a joke, and is not a viable option on this list. Unlike normal gift giving, which could induce the Benjamin Franklin effect, causing the gift giver to like the recipient more, explicitly stating that the giver doesn't expect anything is an attempt to manipulate or guilt-trip the recipient (as is common for people with personality disorders) by increasing pressure to reciprocate. The joke here comes from the idea of giving a psychologist a note relating to the psychology of gift-giving, manipulation, and personality disorders, but this would not be to their enjoyment and should not be done in real life.
|-
| (Title text) Babies or literature but not both || Baby shoes || This is a reference to the six-word story {{w|For sale: baby shoes, never worn}}, sometimes falsely attributed to Ernest Hemingway. Someone involved with babies, such as expecting or new parents, would find baby shoes a valuable gift for their child. Someone interested in literature would see the reference to a famous work. But someone who understands the reference and also enjoys babies might be sad, since the story implies the seller was expecting a baby but something went tragically wrong. This story was previously the subject of [[1540: Hemingway]].
