I own the "The Big Book of Hell" and have looked at it as recently as 5 years ago (although it's with my brother now so I can't check) and I'm pretty sure these are indeed verbatim copies from the "School is Hell" portion.

It's interesting you bring that up, because I thought they were simply lifted from "School is Hell."

I don't know what compilation it showed up in, but the "Bongo's dream dorm" is a re-working of "Bongo's dream house"
