The word swordfish, as a password, refers to a password used first in the 1932 Marx Brothers movie Horse Feathers. The password has since been used in films, TV series, books and videogames.
Swordfish first appeared as a password in the 1932 Marx Brothers movie Horse Feathers—in a scene where Groucho Marx, as Professor Wagstaff, attempts to gain access to a speakeasy guarded by Baravelli (Chico). The original dialogue was:Baravelli
: ...you can't come in unless you give the password.
: Well, what is 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?"
: [laughing] 'At's-a no fish!
: She isn't? Well, she drinks like one! ...Let me see... Is it "Sturgeon"?
: Aw, you-a craze. A "sturgeon", he's a doctor cuts you open when-a you sick. Now I give you one more chance.
: I got it! "Haddock".
: 'At's a-funny, I got a "haddock" too.
: What do you take for a "haddock"?
: Sometimes I take an aspirin, sometimes I take a calomel.
: Y'know, I'd walk a mile for a calomel.
: You mean chocolate calomel? I like-a that too, but you no guess it. [Slams door. Wagstaff knocks again. Baravelli opens peephole again.] Hey, what's-a matter, you no understand English? You can't come in here unless you say, "Swordfish." Now I'll give you one more guess.
: ...swordfish, swordfish... I think I got it. Is it "swordfish"?
: Hah. That's-a it. You guess it.
: Pretty good, eh?
