Can you write a joke with the following setup?
A penguin and a walrus walk into a bar
A penguin and a walrus walk into a bar. The bartender looks up and says, What is this, some kind of Arctic joke? The penguin and walrus just look at each other, confused. Then the walrus shrugs and says, I don't know about Arctic jokes, but we sure know how to break the ice! The penguin rolls his eyes, but can't help but chuckle.
