William and Mildred were married twenty-five years. They decided
   to celebrate with a trip to Las Vegas. When they entered the
   hotel/casino and registered, a sweet young woman dressed in a very
   short skirt, became very friendly. William brushed her off rather
   rudely. Mildred objected, "William, she was nice, that young woman,
   and you were so rude."
       "Mildred, she's a prostitute."
       "I don't believe you. That sweet young thing?
       "Let's go up to our room and I'll prove it." In their room,
   William called down to the desk and asked for Candie to come to room
   1217.
       "Now," he said, "you hide in the bathroom with the door open just
   enough to hear us, okay?" She did. Soon, there was a knock on the
   door. William opened it and Candie walked in, swirling her hips
   provocatively.
       "So, I see you're interested after all," she said.
       William asked, "How much do you charge?"
       "$125 basic rate, $100 tips for special services."
       William was taken aback. "$125! I was thinking more in the range
   of $25."
       Candie laughed derisively. "You must really be a hick if you think
   you can buy sex for that price."
       "Well," said William, "I guess we can't do business. Goodbye."
   After she left, Mildred came out of the bathroom. "I just can't
   believe it."
       William said, "Let's forget it. We'll go have a drink, then eat
   dinner."
       At the bar, as they sipped their cocktails, Candie came up behind
   William pointed slyly at Mildred, and said, "See what you get for
   $25?"
