|The well proportioned though nearsighted secretary like to spend her lunch hour sunbathing on her office building's roof. Wanting an even facial tan, she always left her glasses lying on her desk.|
After a few days, she decided that, since no one could see her anyway, she might as well get a more "overall tan."
No sooner than she had removed her bathing suit and stretched out, but she heard footsteps coming up the stairs. Since she was lying on her stomach, she just pulled her towel over her bottom.
"Excuse me, miss," said the young man. "No one minds you sunbathing up here, but you really should wear a bathing suit."
"What difference does it make?" she asked. `No one can see me up here, and besides, I'm covered with this towel."
"Not exactly," said the embarrassed waiter. "You're lying on the executive dining room skylight!"
