There's a double Decker bus driving down the street full of passengers, blonde and brunette.
On the lower level of the bus, the brunettes are having a good time, talking, laughing, and singing along to the music playing.
On the upper part of the bus, the blondes are seated... they're in a panic.
They're screaming, terrified, and holding onto each other as the bus moves along the street.
Finally, a brunette gets up and walks to the top of the bus to ask what's wrong, and one of the blonde's replies, "what's wrong?!? Well, you'd be screaming too if you didn't have a driver!!!"
