Clocks In Hell

A firefighter died and went to hell where he finds a wall of clocks.

After seeing all these clocks on a wall, with his friends names under them, he asked the devil, what the clocks mean?

- That's easy, each time one of your friends mess up on earth, their clock speeds up one hour. - says the devil.

- I don't see the Chiefs clock anywhere? - the fireman says.

The devil replied:

- Oh him, we have his down in the basement, we're using it for a fan.
