A young secretary was describing her date to a friend. "After dinner," she said, "he wanted to come back to my apartment, but I refused. I told him my mother would worry if I did anything like that."
"Then what happened?"
"He kept insisting, and I kept refusing," the secretary said.
"He didn't weaken your resolve, did he?" the friend asked.
"Not one bit. In the end, we went to his apartment. I figured, let HIS mother worry."
