While the barman is pouring, the man extends his hand at knee height and asks: “Do penguins grow this big?”
“I should think so,” the barman replies.
The man raises his hand. “How about this big?”
“Well, perhaps a king penguin, but I’m not sure . . .”
The man holds his hand at shoulder level: “This big?”
“Not a cat in hell’s chance.”
The man knocks back his drink in one. “Hell. I just ran over a nun.”
