==Explanation==
{{incomplete|Created by a BODY REMOVED FROM AROUND THE APPENDIX OF A BOOK - Do NOT delete this tag too soon.}}

In normal medicine, appendectomy is the surgical removal of an appendix. The purpose of the appendix is not fully understood, believed to be a reservoir for a human's gut microbiome. However if an appendix is swelling, it comes with risk of bursting and causing massive damage through internal bleeding and septic bacterial infection. In such cases the appendix may be partially removed through surgery.

Breaking down the comic's title: circum- means "around," -appendiceal means "the appendix," som(a)- means "the body," and -ectomy means "removal." Therefore, a circumappendiceal somectomy would be "a removal of the body from around the appendix." This appears to be the procedure that the doctor in the comic is describing.

The joke is that such a procedure is functionally identical to a typical appendectomy, the removal of the appendix from the body - just viewed from a different perspective. It humorously implies that the entire body of the patient is the problematic part to be removed, in order to leave behind a healthy, functional appendix.

The title text provides personal insight into the comic. It appears [[Randall]] has gotten appendicitis before, which may have been the inspiration of [[2147: Appendicitis]] and was treated using antibiotics instead of surgery. However, his appendix became inflamed again, and this time it was removed. Randall's experience is not uncommon, as a [https://pubmed.ncbi.nlm.nih.gov/32074268/ 2020 study] found that nearly 40% of patients treated with antibiotics for appendicitis required an appendectomy for recurrent appendicitis within 7 years. As well, this should be the final time, as it is unlikely to get appendicitis without an appendix.{{Citation needed}} However, he does not rule out the possibility that something "extremely unexpected" happened during the surgery which could cause him to suffer from appendicitis again. Possible candidates for such an extremely unexpected event could include the surgeon faking the removal of Randall's appendix and leaving it intact, or removing only part of it, removing Randall's appendix but transplanting someone else's appendix into him instead, or even the appendix's [https://en.wikipedia.org/wiki/Regeneration_(biology) spontaneous regeneration]. While most of these possibilities are absurd{{Citation needed}}, stump appendicitis, in which appendicitis occurs in remnant of the appendix that remains after surgery really does occur in 1 in 50,000 cases according to the article [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1079652/ Appendicitis after appendicectomy - NCBI].

:[Cueball is sitting on a hospital bed, hugging his stomach, possibly in pain as appendicitis causes pain in the appendix. A doctor is speaking to him with one arm outstretched.]
:Doctor: Normally we would remove your appendix from your body.
:Doctor: But thanks to new surgical techniques, we're now able to remove your entire body from around your appendix!

141.101.69.186: Mentioning of Mona Lisa's 1911 theft

It's worth mentioning that unless we're talking an industrial shredder, the Mona Lisa can't be, since unlike most stereotypical paintings, it's actually on glued together pieces of wood and not on Canvas.

Not to say that it wouldn't be damaged heavily by a band of wild rabid dogs, but not "shredded".

Why yes, I am using my art degree, why do you ask?

: Nothing in the original says the dogs are rabid. Mind you, I would expect rabid dogs to go directly after people, not inanimate paintings. [[User:Nutster|Nutster]] ([[User talk:Nutster|talk]]) 22:07, 20 August 2021 (UTC)
:: Our dog shredded our front door once when left alone during a thunderstorm or such. There was even blood left on the broken shards of wood :-(. But I don't think Randall knew that the Mona Lisa was on wood. [[User:Baffo32|Baffo32]] ([[User talk:Baffo32|talk]]) 00:04, 21 August 2021 (UTC)

I don't have an art degree but knew that the painting was on wood. Also, it's "J.C. Penney". I'm guessing Randall was in a hurry on this one.

It make much more sense if the wild dogs didn't get in there by coincidence. Making it about himself would be acceptable if he was the indirect cause of the situation. Revenge successful? [[Special:Contributions/172.69.71.55|172.69.71.55]] 22:03, 20 August 2021 (UTC)

Just checking - I'm not the only one who saw this and immediately googled to see if it was an actual news story, am I? I'm so not plugged into the news that I could honestly have believed that I missed it. [[Special:Contributions/172.70.130.239|172.70.130.239]] 22:09, 20 August 2021 (UTC)
:I also cannot find anything about this. As mentioned above, the painting also cannot really be shredded, as it is on wood, rather than canvas. Edit: Can be shredded, but not really by a pack of dogs. [[User:Theusaf|theusaf]] ([[User talk:Theusaf|talk]]) 23:55, 20 August 2021 (UTC)

Uhh, WHAT? Wood can't be shredded?? Huh/ Tha's news to me . . . . [[Special:Contributions/162.158.74.198|162.158.74.198]] 00:16, 21 August 2021 (UTC)

I'm not convinced it would be THAT big loss for humanity. Sure, the original has some emotional value, but I'm sure we have plenty of backup copies. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 06:01, 21 August 2021 (UTC)

I don't know if it's a coincidence, and if it's worth mentioning, but the Mona Lisa was stolen on 21 August 1911, almost exactly 90 years before the publication of this comic. --[[Special:Contributions/141.101.69.186|141.101.69.186]] 07:10, 21 August 2021 (UTC)

141.101.69.186:

As someone has just Transcripted basically almost all the fine detail I had planned to entable in the Explanation, I shall not now create repetition. Though I had a little more description to the NORXONDOR GOGONAX, in particular, to reference bidirectional (antiparallel) diode pairings (e.g. an LED assembly that glows a different hue depending upon the applied current bias) as probable inspiration, and that latched Flip-Flops surely inspired some part of the Frankensteinian gate-types, too. [[Special:Contributions/141.101.99.119|141.101.99.119]] 00:08, 3 August 2021 (UTC)

(Also, surprised there was no direct "GONDOR" reference. Or maybe that's because it was ''too'' obvious?) [[Special:Contributions/141.101.99.211|141.101.99.211]] 00:12, 3 August 2021 (UTC)

: I was also missing a "GONDOR" reference, and all the X's also made me think XEHANORT. [[Special:Contributions/172.70.126.174|172.70.126.174]] 03:49, 3 August 2021 (UTC)

...So, who's ready to draw up some truth tables? [[Special:Contributions/172.70.126.211|172.70.126.211]] 01:22, 3 August 2021 (UTC)

I can't get the lines in the bitwise-operation example to align properly; the first one is indented a tad. Can someone please fix that? Thanks... [[User:BunsenH|BunsenH]] ([[User talk:BunsenH|talk]]) 04:11, 3 August 2021 (UTC)

The symbol for norx gate (1-input OR, two outputs) I'd read as a noninverting buffer to increase another gate's usable fan-out. Xand gort resembles the symbol for an [[wikipedia:Operational amplifier|op-amp]]. Given the subtraction that an op-amp does, the xand gort's truth table probably resembles that of the [[wikipedia:Material conditional|"implies" operator]]. [[User:Tepples|Tepples]] ([[User talk:Tepples|talk]]) 04:23, 3 August 2021 (UTC)

the "NORG XORT" is not equivalent to an XOR, as the symbol is round on the right. --[[Special:Contributions/141.101.69.186|141.101.69.186]] 06:39, 3 August 2021 (UTC)
