A guy is walking down the street and he's really horny. So he goes to the first whorehouse he sees. He only has five dollars, so they kick him out. The guy goes to the next brothel. But since he has only five dollars, they kick him out as well. By this time he is super horny, so he goes to the next brothel and says, "Look, I only have five dollars. I'm really horny and I need a blow job!"
The manager takes pity on him and says, "OK, for five dollars I can give you a penguin!"
"What's a penguin?" he asks.
The manager grins, "You'll find out!"
He takes the five dollars and leads the horny man into a bedroom. The horny guy unzips his pants and waits for the penguin. Soon a whore comes in and starts giving the guy a really hot blow job. Just as he is about to come, she stops and walks away. The horny guy waddles after her with his pants around his ankles, shouting,"HEY! WHAT THE FUCK IS A PENGUIN?!"
