I Love Lucy Season 4 Episode 6

(Lucy enters the living room dressed as Marilyn Monroe)
Ethel: Hey, who are you supposed to be?
Lucy: Guess.
Fred: Humphrey Bogart in a wig.

Pete, the grocery boy: But, Mrs. Ricardo, when I play the trumpet, I'm real gone.
Lucy: (shooing Pete out of the apartment) Then go, man, go!

Ricky: Mr. Benjamin, that sounds very, very exciting. Is it gonna be Cinemascopy and Stereonophic?
Mr. Benjamin: I beg your pardon?
Ricky: Is it gonna be Cinemascopy and Stereonophic?
Lucy: Mr. Benjamin, I think he means Cinemascope and Stereophonic.
Ricky: That's what I said!

Ricky: Would you leave me alone? I've been in show business a long time.
Lucy: It doesn't make you an actor just because you've been shouting "Babalu" and beating on a cowhide.

(Lucy is giving Ricky some acting tips.)
Fred: What do you want him to do?
Lucy: For one thing, I would like him to develop a distinctive way of speaking.
Fred & Ethel: Ricky?

Lucy: How did they find out?
Ethel: I don't know, I didn't tell anybody. Did you?
Lucy: Certainly not. I didn't tell a soul and they all promised to keep it a secret.
