Two bowling teams, one of all Blondes and one of all 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 Blonde team rides on the top level. The Brunette team down below is whooping it up having a great time, when one of them realizes she doesn't hear anything from the Blondes upstairs.

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.

The brunette asks, "What the heck's going on up here?  We're having a great time downstairs!"

One of the Blondes looks up at her, swallows hard and says,

"YEAH, BUT YOU'VE GOT A DRIVER ."
