Purple Polka-dotted Penguin
A purple polka-dotted penguin goes into a bar and orders a White Russian. The bartender mixes it up, gives it to the penguin, and he drinks it. When the penguin asks for his tab, the bartender charges him $20.00. Reluctantly, the penguin slams the money down on the counter and gets up to leave.
"Hey, wait!" the bartender yelled after him. "We don't get too many purple polka-dotted penguins in here."
The penguin turns around and yells "At $20.00 for a White Russian, I should think not!"
