Eats, shoots, and leaves.
These are comics that somebody thought were pretty good, or even full LOL, and not baffling but a little hard to pin down. Like, you can think of a rather plausible explanation of the chuckle — or maybe two! — but there’s nothing that clinches the case that *this* or *that* just has to be the key to what’s going on.
For example, with something like this Andertoons, we might think of the minor mystery as expressed in terms of providing the missing caption. Is it about the odd feeling you’re being watched? Or more like “Oh, where did I set down my glasses?”. It could be either, do you agree?
A Minor Mystery from Darren, who says “I can’t tell if Watson’s jarns need to be interpreted as a specific term. I’m flummoxed. Apparently the squirrel is as well?”
Okay, the joke here is that the threatened punishment will involve a cannister vacuum cleaner (in what seems to be a photo clip?) rather than a conventional physical beating or the like. But it’s an unanswerable mystery just what the threat is. Torture by exposure to noisy motor, like a household pet? Being inhaled altogether? Having some portion of his body inhaled?
