This one doesn't read very well, but it can be real fun if you act it out properly: A guy goes to a whore and asks her about her rates.

"Well", she says, "basic service is $25. The 'Pink Panther' is $50. And if you want something really special, I can do you 'The Penguin' for $100."

"Hmmm, that sounds interesting", says the guy, "Allright, I'll go for 'The Penguin' ".

The whore loosens his belt and pulls his jeans down to his knees.

"Money first", she says, and he brings out his wallet.

The whore takes his money and just walks away. The guy runs after her with his pants down. (imitate a waddling penguin here)

"Hey! where are you going!"
