Jill and her boyfriend, Jack, were setting at home one night and became bored. "Hey, let's play a game," Jill said.
"What game?" was Jack's bored reply.
"Let's play hide'n'seek," answered Jill. "I'll have wild sex with you if you can find me."
"What if I can't find you?" asked Jack.
"I'll be behind the piano!" said Jill.
