Wearing a ski mask and carrying a gun, a thief burst into the
bank one day.  Aiming his gun at the guard, the thief yelled,
"FREEZE, MOTHER-STICKERS,  THIS IS A ****-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 would-be
thief ran away and is still at large.
