Two bowling teams, one all blondes, one all bruneettes, charter a double-decker bus for a weekend bowling tournament in Atlantic City.
The brunette team rides on the bottom level of the bus, the blonde team rides on the top level.
The brunette team, down below, is wooping it up and having a great time until one of them realizes she doesn't hear anything from the blondes upstairs, and she decides to investigate.
When the brunette reaches the top, she finds the blonde team staring straight ahead at the road, frozen in fear, clutching the seats in frount of them with white knuckles.
"Whats going on up here?" asks the brunette. "We're having a great time downstairs!"
"Yeah," screams a terrified blonde, "but you've got a driver!"
