Horse Feathers (1932) is a Pre-Code Marx Brothers film comedy. It stars the four Marx Brothers (Groucho, Chico, Harpo and Zeppo) and Thelma Todd. It was written by Bert Kalmar, Harry Ruby, S. J. Perelman, and Will B. Johnstone. Kalmar and Ruby also wrote some of the original music for the film. Several of the film's gags were taken from the Marx Brothers' stage comedy from the 1900s, Fun in Hi Skule. Wikipedia
Baravelli: (through speakeasy's door) Who are you? Professor Wagstaff: I'm fine, thanks, who are you? Baravelli: I'm fine too, but you can't come in unless you give the password. Professor Wagstaff: Well, what is the password? Baravelli: Aw, no. You gotta tell me. Hey, I tell what I do. I give you three guesses. It's the name of a fish. Professor Wagstaff: Is it Mary? Baravelli: Ha-ha. That's-a no fish. Professor Wagstaff: She isn't? Well, she drinks like one. Let me see: Is it sturgeon? Baravelli: Hey, you crazy. Sturgeon, he's a doctor cuts you open when-a you sick. Now I give you one more chance. Professor Wagstaff: I got it. Haddock. Baravelli: That's-a funny. I gotta haddock, too. Professor Wagstaff: What do you take for a haddock? Baravelli: Well-a, sometimes I take-a aspirin, sometimes I take-a Calamel. Professor Wagstaff: Say, I'd walk a mile for a Calamel. Baravelli: You mean chocolate calamel. I like that too, but you no guess it. 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. Professor Wagstaff: ...swordfish, swordfish... I think I got it. Is it "swordfish"? Baravelli: Hah. That's-a it. You guess it. Professor Wagstaff: Pretty good, eh?
