Wearing a ski mask and carrying a gun, a thief burst into a bank one day.

Aiming his gun at the guard, the thief yelled, "Freeze, mother stickers, this is a f--- up!

For a moment, everyone was silent. Then the snickers started. The guard completely lost it and doubled over laughing. It probably saved his life, because he'd been about to draw his gun. He couldn't have drawn and fired before the thief got him.

The thief ran away.

The bank, in memory of the event, put a plaque on the wall - "Freeze, Mother-Stickers, this is a F--- Up!"
