A man walks into a bar, orders a bourbon, neat, and downs it in a single gulp.
“How big is a penguin?” he asks the bartender.
The bartender says, “Around 18 inches.”
He orders a double bourbon, neat, and gulps it down.
“What’s the biggest a penguin can ever be?”
The barman frowns. “Three feet, maybe an inch or two more.”
The man orders another double bourbon, neat, and gulps it down even quicker.
He sighs. “I may have run over a nun.”
