At one ad agency, a guy in production was fired when they discovered he was The Xerox Flasher. Every morning, he Xeroxed his privates, made copies & left them in the secretary's desks.
The boss said "Hell, he's the only person in the building who isn't guilty of false advertising!"
His secretary said "Well, not exactly."
He said "Oh God! Don't tell me!"
She said "Yes, sir. He was using the enlarger."
