Two factory workers, a fat man and a blonde woman, are talking.

"I think I'll take some time off from work today," says the fat man.

"How do you think you'll do that?" says the blonde. "You know the boss never lets anyone go home unless they're sick."

"Just watch," says the fat man, laughing.

The fat man strips off his shoes, and laboriously climbs up to the rafters; then hangs upside down from one of the overhead beams.

A few minutes later, the boss walks in, and sees the fat man hanging from the ceiling

"What the hell do you think you're doing?" asks the boss.

"I'm a light bulb!" answers the fat man, grinning.

"I think you need some time off," says the boss, shaking his head sadly.

So, the fat man climbs down from the ceiling and walks out of the factory.
