A guy is walking down the street, and he's really horny. So he goes to the
first whore house he sees. He only has five dollars, so they kick him out.

The guy goes to the next one. But since he only has five dollars, he gets
kicked out again.

By this time he's really super horny, so he goes to the next one and says,
"Look, I only have five dollars. I'm really horny, and I need a blow-job for 5
dollars!"

The guy there says, "OK. For five dollars we can give you a penguin."

"What's a penguin?"

"You'll see."

So, the guy takes the $5 and leads the horny man to a bedroom. The horny man
unzips his pants, and waits for his "penguin."  Soon a whore comes in and
starts giving the guy a blow job. Just as he's about to let loose, she stops
and walks away. Now the horny guy, with his pants at his ankles, waddles after
her, shouting "HEY! WHAT'S A PENGUIN?"
