Well...this reminds me of something
Our school volleyball team was on the way to a match(they were riding a bus there), and they started making jokes about eachother. Soon they got to short bus jokes(you rode the short bus, your mom rode the short bus...etc..). After about a minute of this, one of the girls on the bus said "stop that, my brother rides the short bus." You could've heard a pin drop for the next 5 minutes, rofl.
