}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
[[Megan]] has been haunted by a ''Timeghost'' for some time. It is obviously not the first time the ghost arrives to let Megan know that &amp;quot;...ooOOOOOOOOooo... Tiiiime is passiiiing!&amp;quot; The ghost is dedicated to making people feel old by having them think about the passage of time. It is shown to reference time periods related to well-known people and events, such as famous actors and the release of movies and TV shows. Megan is just annoyed that it is back and wishes it to go away.&lt;br /&gt;
&lt;br /&gt;
But then when [[Cueball]] ask &amp;quot;How long has it been doing this?&amp;quot; the ghost suddenly predicts that Megan and Cueball will die in a shorter amount of time than the time that has passed since the ghost began its hauntings. This disturbs Megan who stops her complaining and asks &amp;quot;'''What!?'''&amp;quot; This is not the first time she has been haunted by the ghost but it has probably not been that long, so this is a very scary thought to her (and Cueball).&lt;br /&gt;
&lt;br /&gt;
We do, however, not know how long the ghost has been haunting Megan. Also the &amp;quot;staaaaart of my haunting&amp;quot; may refer to the first time the ghost haunted anyone, not just Megan. This could be a long time ago and thus be true for anyone it meets today. Or it could mean since the start of this particular manifestation, meaning their deaths are imminent! It is also possible Timeghost is being deliberately ambiguous in an effort to frighten them even more. This is of course only scary if you believe the ghost can predict the future, which is not what it has been doing so far. There is no example in the comic where it makes a prediction that we know is accurate - only comparing time spans we can look up - see below. An alternative interpretation of the last panel is that the ghost is going to kill Cueball and Megan soon.&lt;br /&gt;
&lt;br /&gt;
But one thing about the prediction is true - they will eventually '''die'''. And this is the scary part about realizing how old you are and that you are quickly getting older: You will die, and &amp;quot;[[Time Vulture|soon]]&amp;quot; (for some value thereof).&lt;br /&gt;
&lt;br /&gt;
The comic seems to be using &amp;quot;factoid&amp;quot; to mean a small fact. &amp;quot;{{w|Factoid}}&amp;quot; can also mean a &amp;quot;questionable or spurious statement presented as a fact&amp;quot;, but this does not seem to be intended usage here. In this instance, some of the factoids are easily verifiable, while others are reasonable assumptions based on the number of years passed since the individual events. Several sources advocate the use of the word &amp;quot;factlet&amp;quot; to express a brief interesting fact, while using the word &amp;quot;factoid&amp;quot; for unverifiable or untrue statements passed as fact.&lt;br /&gt;
&lt;br /&gt;
While ''factoids'' tend only to have mostly only entertainment value, the last ''fact'' from the ghost is a prediction of the future (Megan and Cueball's death) which is actually of some practical value if it can be trusted.&lt;br /&gt;
&lt;br /&gt;
&amp;quot;Timeghost&amp;quot; might be a literal interpretation of {{w|Zeitgeist}}, which is a German term for &amp;quot;spirit of time&amp;quot; and refers to the school of thought that influences or dominates the art and culture of a time period. All the events and people mentioned in this comic may be considered influences on present day art and culture.&lt;br /&gt;
&lt;br /&gt;
In the title text, Megan calls {{w|Ghostbusters}} (from the 1984 movie) to help get rid of the Timeghost. This of course makes the ghost state that &amp;quot;people born years after that movie came out are having a second chiiiild right now&amp;quot; making her feel old once more.&lt;br /&gt;
&lt;br /&gt;
[[Randall]] has covered making people feel old several times in [[647: Scary]], [[891: Movie Ages]], [[973: MTV Generation]] (in which White Hat utters Cueball's &amp;quot;That can't be right&amp;quot; line), and [[1477: Star Wars]]. Also see the blag post [http://blog.xkcd.com/2012/09/29/odd-temporal-milestones/ Odd Temporal Milestones]. This is, however, so far the only one that makes a prediction of anyone's death. A similar ghost with a much different agenda was seen in [[1108: Cautionary Ghost]]. Similarly annoying fact(oids) were given in [[1272: Shadowfacts]]. [[926: Time Vulture]]s make you feel old because the entire remainder of your life is only perceived as a few moments by them.&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
This was the thirty-fifth comic originally posted to [[LiveJournal]]. The previous one was [[32: Pillar]], and the next one was [[41: Old Drawing]].&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Explain the joke in the title text.}}[[:Category:Self-reference|Self-reference]] is a situation where something (a comic, a drawing, a musical work, a novel, a mathematical theorem) refers to itself in some manner. This can be a powerful technique in art, music, mathematics, and computer science (it is the basis of recursion). In this comic, [[Cueball]] promises not to use self-reference for humor, and then realizes after a beat panel that, since this comic is referring to the series of comics he is part of, he is using self-reference, thus breaking his promise. Without the last panel, this comic wouldn't be funny, and therefore wouldn't break the promise about using self-reference for humor. But with it, and his realization that he is breaking his promise, it does break that promise. Self-references have been used most famously later in [[688: Self-Description]], but was already used in [[6: Irony]] and also in [[:Category:Self-reference|other comics]]. The webcomic Comic JK made a [https://web.archive.org/web/20140323234759/http://comicjk.com/comic.php/44 spoof of this comic].&lt;br /&gt;
&lt;br /&gt;
The title text is just another humorous self-reference, which cites itself as a reason for Cueball/Randall thinking about self-reference, becoming self-referential in the process.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[Cueball is standing alone.]&lt;br /&gt;
:Cueball: I promise to never again squeeze humor out of self-reference.&lt;br /&gt;
&lt;br /&gt;
:[Beat panel.]&lt;br /&gt;
&lt;br /&gt;
:[Cueball is standing alone.]&lt;br /&gt;
:Cueball: God dammit.&lt;br /&gt;
&lt;br /&gt;
==Trivia==&lt;br /&gt;
The original title of the comic was wrong, as this comic was released on a Monday, not a Friday. The [[32: Pillar|previous comic]] was actually supposed to come out on a Friday, but [[Randall Munroe|Randall]] forgot to post it in time and released in on a Saturday. See more on [[32: Pillar#Explanation|that comic's explanation]].&lt;br /&gt;
