Speaking Of Crabs Growing An Extra Claw. . .

One of my favorite Rodney Dangerfield jokes, "Hey, I'll tell ya, I get no respect. The other night I went out for a fancy dinner and the waiter brung me a lobster with only one claw. I says, hey! What gives?! He said, I'm sorry sir, sometimes they fight in the tank. So I said, well bring me the one that won!"

Edit: stupid homophones.
