Groucho and Chico Marx in “Horse Feathers”

Who are you?

I’m fine, thanks. Who are you?

I’m fine, too, but you can’t come in unless you give the password.

Aw no, you gotta tell me! Hey, I tell what I do I give you three guesses. It’s the name of a fish.

Is it Mary?

Ha! That’s a no fish.

She isn’t? Well, she drinks like one!
