It was one of the “what’s the difference between” jokes, where there are two things to contrast, and the difference I intended to highlight was not the obvious one, it was in fact an incongruous minor difference. I think some amount of wordplay was involved, and also a secondary meaning of some sort, such as the the two things I set out to contrast being in fact much more similar than it would appear.

Anyway, it was it was an above-average joke, I’m a little disappointed I can’t remember it. Any chance you guys can help me out based on that description?
