A man drives to a gas station and has his tank filled up. While doing this the clerk spots two penguins sitting on the back seat of the car.

He asks the driver, "What's up with the penguins in the back seat?"
The man in the car says, "I found them. I asked myself what to do with them but, I haven't a clue."
The clerk ponders a bit then says, "You should take them to the zoo."
"Yeah, that's a good idea," says the man in the car and drives away.

The next day the man with the car is back at the same gas station. The clerk sees the penguins are still in the back seat of the car.
"Hey, they're still here! I thought you were going to take them to the zoo!"
"Oh, I did," says the driver, "and we had a swell time. Today I'm taking them to the beach."
