A man is strolling round city when he sees a bar with an indication promoting “All of the Beer You Can Drink for $1!”
He thinks that’s a terrific deal so he goes in, sits down, fingers the bartender a greenback, and asks for a beer.
“Positive, straight away” says the bartender as he pulls out a tiny shot glass and fills it up midway.
The person is shocked. “What the hell is that this?” he asks.
“That’s all of the beer you may drink for $1.”
