Blondes, Brunettes and a double decker

[Gypsy]

Two bowling teams, one of all Blondes and one of all Brunettes, charter a double-decker bus for a weekend bowling tournament in Brisbane. The Brunette team rode on the bottom of the bus, and the Blonde team rode on the top level. The Brunette team down below really whooped it up, having a great time, when one of them realized she hasn't heard anything from the Blondes upstairs.

She decided to go up and investigate. When the Brunette reached the top, she found all the Blondes frozen in fear, staring straight-ahead at the road, clutching the seats in front of them with white knuckles.

The brunette asked, "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 whispered, "YEAH, BUT YOU'VE GOT A DRIVER."
