A trucker who had driven his fully loaded rig to the top of a steep hill and was just starting down the equally steep other side when he noticed a man and a woman lying in the center of the road, making love. He blew his air horn several times as he was bearing down on them. Realizing that they were not about to get our of his way he slammed on his brakes and stopped just inches from them. Getting out of the cab, madder than hell, the trucker walked to the front of the cab and looked down at the two, still in the road, and yelled, "What the hell's the matter with you two? Didn't you hear me blowing the horn? You could've been killed!"
The man on the highway, obviously satisfied and not too concerned, looked up and said, "Look, I was coming, she was coming, and you were coming. You were the only one with brakes."
