XKCD Web Comic #986: Drinking Fountains (described)

A web comic of romance, sarcasm, math, and language.

Scene: Drawing of a stick figure exiting a restroom. A drinking fountain hangs on the wall next to the restroom door.  A thick black arrow points right to the next scene, which is the same scene, but the stick figure is shown drinking from the fountain. A thick black arrow points down and left to the next scene, which is the same scene, except the stick figure is going back into the restroom. A thick black arrow points up and left to the original scene with the stick figure coming out of the restroom.

Caption: I avoid drinking fountains outside of bathrooms because I’m afraid of getting trapped in a loop.

Hover text: I’ve always wondered whether you could drink slowly enough, and eliminate fast enough, that you just sort of peed continuously. But I’m afraid to try because I worry someone might call while I’m doing it and ask what I’m up to, and I won’t be able to think of a lie.

Warning: this comic occasionally contains strong language (which may be unsuitable for children), unusual humor (which may be unsuitable for adults), and advanced mathematics (which may be unsuitable for liberal-arts majors).
