They probably also would not understand that having to explain a joke removes the funny. Especially when they have to explain each. and. every. one.

A friend of mine from years ago back when I lived in a libland town was trying out a stand-up routine. I probably am not recalling correctly, but after some "meh" jokes, he ended with a joke like "at least it is not as small as Trump's dick"
surprisinlyg enough, (or maybe not) he got laughs for the end.
