Time off

Two men working in a facory were talking. I know how to get some time off, said one.

How are you going to do that?

Watch, he said, and climbed up on a rafter. The foreman asked what he was doing up there, and the man replied.I--m a lightbulb.

I think you need some time off, the foreman said said, and the first man walked out of the factory. After a moment, the second man followed him.

where do you think you--re going? the foreman shouted.

I can--t work in the dark, he said.
