Little Johnny's Alphabet

Little Johnny is in class. The teacher is going through the alphabet, having each child think up a word that starts with a letter. They get to "W", and the teacher figures Little Johnny can't think up anything dirty with a "W" so she calls on him. "Womb!", Little Johnny says. "That's a good word, Johnny", teacher says. "Is that as in, where babies come from?" she asks. "No," says Johnny, "that's the sound elephants make when they're screwing, you know, 'Womb! Womb! Womb!"

Penguins on Tour

A motorist pulls up to the gas pumps and says, "Fill it up, please". The Attendant notices that the front and back seats of the car are occupied by penguins. "Hey Buddy," says the attendant to the driver, "These birds can't be happy like this... they're wild animals, you should take them to a zoo or something.." The motorist agrees to do so.
The next day the guy drives into the filling station and once again the attendant sees the penguins sitting in the front and back seats, and they are all wearing sunglasses and holding towels... "What's this?" he says to the driver, "I thought you agreed to take these birds to the zoo?"
The driver says, "I did... and they had such a great time that today I'm taking them to the beach."
