are other people in the comments here interpreting this as a sexual pun, “choking on pussy?” I don’t think that’s how Gary Larson intended it.
Because first of all, cunnilingus has nothing to do with putting that anatomical part down one’s throat. It’s impossible. You can put a penis down your throat but you don’t put pussy down your throat.
And second of all, Gary Larson’s humor is rarely (if ever?) sexually crass.
