Bill was sitting having a few at the local bar when he saw a very lovely young woman (Amy) sitting only a few chairs down. He moved over and proceeded to engage her in general conversation, finally mustering up his courage to ask her out to a movie.
Amy hauled off and slugged him so hard he landed on his ass on the floor.
"Gee," Bill said, picking himself up, "I guess a blowjob is out of the question, huh?"
