An Amy Hwang cartoon in the latest — 10/23 — issue of the New Yorker that I found hugely funny, for reasons I couldn’t at first explain:
(#1)
Well, there are people who can fall asleep (pretty much) anywhere, as they say — I’ve been such a person for about 70 years now — but I have never just lain down for an impromptu nap on the ground out in the world, as the snail in #1 seems to have done, preposterously.
Actually, the cartoon snail is lying flat as a flounder, in such a way that it’s hard to be sure that it’s only somnolent and not in fact deceased. It could well be not merely sleeping, but dead — reversing the customary formula, of many applicabilities, that someone or something isn’t dead, but only sleeping. Snail3 in the cartoon looks a lot like the Monty Python pet-shop parrot: this is an ex-snail, gone to meet its maker, and its snail buddies are just slip-sliding along in denial.
So #1 is wonderfully absurd. It’s also an excellent example of a cartoon existing equally in two worlds: visually, the world of snails (lacking males, since snails are generally hermaphroditic; bereft of speech; and also exhibiting dormancy but not, apparently, actual sleep); behaviorally, the world of human beings (where Snail1 can remark that he — Snail3 — can fall asleep anywhere).
But then I was carried away into the complexities of sleep in human beings and in other creatures (where it contrasts with rest and dormancy, not to mention death) and into the behavior of snails, where I will report — surprise! — on a 2011 study from the Journal of Experimental Biology about a common pond snail:
