Teacher: Tim, where are your parents? It's been 15 minutes!
Tim (Orphan): Yeah um, they can't come.
Teacher: Why not?
Tim: They're too busy working in heaven.

Hey, check it, nimrod! The joke is funny because Tim is an orphan, meaning his parents are dead. When the teacher asks why his parents aren't around, he says they are "working in heaven," which is a roundabout way of saying they are dead without directly stating it. You probably think that work is fun! You're such a loser!
