It was Spring Break for the collage kids and a group of blondes and brunettes decide to rent a double-decker bus and go on a trip. The brunettes are to be on the bottom and the blondes on the top. The bus had been driving a little bit and the brunettes were having a party. They were drinking, smoking, dancing, etc. Well when they listened, they didn't hear anything up on the top deck.
One of the brunettes decide to go check it out. The brunette walks up the stairs and sees all the blondes with there eyes shut, hands over there mouth, and shaking. The brunette goes up to one of the blondes and says, "What's wrong? We are down stairs having a party and having loads of fun." The blonde replies, "You guys have a driver, we don't!"
