Liana was a beautiful girl. As she was walking through the woods on a hot summers day, the heat became too much for her and she decided to go for a swim. She took off all her clothes, piled them neatly on the side of the riverbank and dived in.
A couple of young boys came along and decided to steal her clothes.
Having climbed out of the water and discovered her clothes had been stolen, Liana decided to go to the roadside and hitch a ride home.
Along came Steve, riding a bicycle. He stopped for Liana. "Come," he said, "I'll ride you into town."
She jumped on his bicycle and rode side-saddle in front of him. Steve said nothing, but after ten minutes Liana was so overwhelmed at how calm he was that she said, "Tell me, haven't you noticed that I'm completely naked?"
"Sure," said Steve. "Haven't you noticed that you're riding on a girls bike?"
