I had a threesome on an elevator with a monkey and my underage, deaf, & mentally challenged sister...
It was wrong on so many levels.

Okay, listen up, buttercup. The joke is a play on words. The guy ain't talking about moral issues, he's talking about the elevator going up and down! It's "wrong on so many levels" because they were literally on different floors. You probably still take the stairs, don't you?
