This is real niche, but there is a figure of speech, "A pun is the lowest form of humor."
Some genius later invented a story about a group of comedians who get lost in the mountains with only two books: a collection of puns, and a naturalist's guide to mountain cats. They were getting stalked by something, and so - hoping to get some advice on surviving - they flipped to the section on pumas, and learned that puma species are named after conquerors. The Carthaginian puma is seen on the highest peaks. The Mongol puma is seen in middle elevations.
One of the comedians points out that they're actually in a mountain valley, at a pretty low elevation. So what cat is this the habitat for?
Well it turns out, "A Hun is the lowest form of puma."

I'd just remembered that joke when I needed to come up with a name for the evil ocean pirate plane in the Gyre.
