Mister Peckerhead enters a pub, sits down at the bar – then orders a double whiskey on the rocks.
After he finishes the whiskey, he peeks inside his shirt pocket – then orders another double whiskey.
After he finishes that one, he peeks inside his shirt pocket again – and orders the same drink again.
The bartender says; “Look buddy – I’ll bring you whiskey all night long, but you gotta tell me why you keep looking inside your shirt pocket before you order every drink.”
Mister Peckerhead replies; “I’m looking at a photo of my wife, so I know when to go home. I’ll go home, when she starts looking good.”
