A rather well built woman, Joan, spent almost all of her vacation time sunbathing on the roof of her hotel. The first day she sunbathed, she wore a red bathing suit. However on the second day, she felt a little more adventurous. She slipped out of it in order to get an overall tan figuring that no one could see her way up there. She'd hardly began when she heard someone running up the stairs. She was lying on her stomach, so she just pulled a towel over her rear.

"Excuse me, miss," said a flustered little (out of breath) assistant manager of the hotel. "The Hilton doesn't mind you sunbathing on the roof, but we would very much appreciate you wearing a bathing suit as you did yesterday!"

"What difference does it make", Joan asked rather calmly. "No one can see me up here on the roof and besides, I'm covered with a towel."

"With all due respect, not exactly ma'am," said the embarrassed little man. "You are lying on the dining room skylight."
