 Two factory workers are talking. The woman says, “I know how to get some time off from work!”

“How?” asks the man.

“Watch this,” she says.

She climbs up to a rafter, hangs upside down, and starts swaying back and forth.

The boss walks in, sees her, and shouts, “What on earth are you doing?”

“I’m a lightbulb!” she exclaims.

The boss sighs. “You’ve been working too hard. Go home and take the rest of the week off to rest.”

She climbs down, winks at her coworker, and heads for the door.

The man suddenly starts following her.

The boss stops him and asks, “Where do you think you’re going?”

He shrugs and says, “Well, you can’t expect me to work in the dark, can you?”
