BRAKES
As the truck driver came flying over the top of a steep hill, he spotted
two figures in his path rolling around in the middle of the road. 

The driver blew his horn and braked frantically, but the couple continued
their love making, in spite of his warnings. 

The truck finally slid to a halt barely three inches from the pair. "Are
you crazy?" The driver shouted at them. "You could have been killed!" 

The man stood up and faced the driver. "Well, I was coming, she was
coming and you were coming," He panted, "And you were the only one with
brakes."
