Well, not ANY song, technically- but Zappa did enjoy writing songs about weirdos.
Disco Boy and Dancin’ Fool are two songs that come to mind immediately, but I’m sure there are some other songs like that. Hell, Joe’s Garage is a whole concept album centred around a bit of a weirdo!
I’d recommend his songs in general, but if you want some slightly funny descriptions, his discography is there.
