From "Monty Python and the Holy Grail" (1975). Need we say more? Ni!

You don't have to speak Vietnamese to get the gist of what the guard yells at Nick (Christopher Walken) in the first Russian roulette scene in "The Deer Hunter" (1978).
During a tutorial in "Cabaret" (1972), a proper young lady innocently asks the meaning of the English term "screwing." Sally Bowles (Liza Minelli) reflects for a moment, then helpfully supplies the only German word she's able to pronounce perfectly.

Norman Bates (Anthony Perkins) reacts to Mom's handiwork after the shower scene in "Psycho" (1960)
Frau Blucher (Cloris Leachman) tempts the doctor (Gene Wilder) with a warm beverage in Mel Brooks' 1974 comedy, "Young Frankenstein."
Ben Braddock (Dustin Hoffman) receives pithy career advice in "The Graduate" (1967).
Among the completely random words alcoholic attorney George Hanson (Jack Nicholson) blurts out each time he drinks his Jim Beam in "Easy Rider" (1969), this one somehow stands out.
When Bill (Garry Merrill) tenderly says "I love you" in the 1950 talkfest "All About Eve," Margo Channing (Bette Davis) responds with a single syllable.
Wayne and Garth (Mike Myers and Dana Carvey) bestow their highest praise on a Guess ad featuring Claudia Schiffer in "Wayne's World" (1992).

The famous French mime Marcel Marceau says the only word uttered out loud in Mel Brooks' 1976 "Silent Movie."
From the 1947 film noir "Dead Reckoning." When you hear it — the word World War II paratrooper Captain Rip Murdock (Humphrey Bogart) and his missing buddy used to yell just before jumping out of a plane — there's a good chance someone is about to die.
It's the cryptic word Danny (Danny Lloyd) writes in lipstick on the bathroom door — to be read backward in the bedroom mirror — in Stanley Kubrick's 1980 adaptation of "The Shining."

After going the distance in "Rocky," Sylvester Stallone's 1976 breakout hit, the title character summons his girlfriend.
