This may belong in Nonesense, but I'll start here. You mods know if it needs to be moved.
So I'm watching the local news the other night and they do a report on a bank robbery. The couple, a man and a woman, do nothing to disguise themselves and the cameras have a crystal clear image of them. Anybody who knew either of these two would easily identify them.
But, just in case nobody recognized them, they made it even easier by writing the note that they handed to the teller on the back of a PERSONAL CHECK! Yeah, their own account! I'd say this goes in the dumb vault!
