Mary said, “Bob, that young lady was nice and polite, and you were very rude.”
“Mary, she’s a call girl.”
“I can't believe that! That sweet young thing?”
“Let’s go up to the hotel room and I’ll prove she's a call girl.”
They entered the room and Bob called down to the reception desk and asked for ‘Heather’ to come to his room. “OK,” he said to his wife, “you hide in the closet with the door open just enough to hear us.” After about four or five minutes, there was a knock on the door. Bob opened it and Heather walked right in, looking very attractive.
Bob asked, “What do you charge for sex?”
“$200 per hour,” Heather responded.
“$200 per hour! I was thinking more around $50 per hour.” Bob said.
“You must be crazy if you think you can get sex at that low price.” Heather replied.
“Well, that's too high.” said Bob, “I guess you should just leave, Heather.”
After she left, Mary came out of the closet. She said, “I can’t believe it, but you were correct!”
Bob said, “Let’s forget all about it. Why don't we go have a drink.”
At the pub as they sipped their drinks, Heather came up behind Bob, pointed at Mary, and said, “See what you get for $50?”
