A bus crashes full of ugly people. They all go to heaven.

God says they have one wish each. The first one wishes he is beautiful. The man at the back of the line laughs for a bit. The second one wishes the same as the first one. The man at the back laughs again.

This goes on until it comes the the guy at the end who is rolling with laugher.

God says him "what do you wish for?". He says "for all the people who wished to be beautiful to be ugly again".
