Two bowling teams, one of all blondes and one of al brunettes, charter a double-decker bus for a weekend bowling tournament in Atlantic City.
The brunette team rides on the bottom of the bus. The blond team rides on the top level.
The brunette team down below is whooping it up and having a great time, when one of them realizes she doesn't hear anything from the blondes upatairs. She decides to get up and investigate.
When the brunette reaches the top, she finds all the blondes frozen in fear, staring straight ahead at the road, and clutching the seats in front of them with white knuckles.
She says, "What the heck's going on up here?" We're having a great time downstairs!"
One of the blondes from the second team looks up and says, "YEAH, BUT YOU'VE GOT A DRIVER!"
