A woman went up to the roof-deck of her hotel to sunbathe. No one else was there, so she slipped out of her swimsuit to get an overall tan. A few minutes later, she heard someone running up the stairs.
“Excuse me, miss,” said the hotel manager. “We would appreciate it if you wore a bathing suit.”
“But I’m alone,” she said. “What difference does it make?”
“A lot,” said the manager. “You’re lying on the dining room skylight.”
