What does a cannibal do after he dumps his girlfriend?
He wipes his butt.
Listen up, buttercup. So, like, cannibals eat people, right? And when this cannibal dumps his girlfriend, he's gotta "wipe his butt" because, get it? He probably ate her. This is funny because it's gross and unexpected. You are probably wiping your butt right now. Just kidding... unless?
