Gabe: Now, I have decided to give all you guys one more chance. (holds up a finger) Now count it. One.
Vinnie, Freddie, and Arnold: One.
(after the Sweathogs' papers got F's)
Vinnie: Five bucks for an F, Epstein! I coulda done it for free and gotten one!
(Angie asks the other Sweathogs about their term paper subjects)
Angie: I was thinking about doing mine on Marilyn Monroe.
Freddie: Well, why stop there? Why not do all those bleach blonds and call it 'Roots?'
Juan: How'd you figure it was Cavelli, pop?
Kotter: Ah, good question, number one son. Old Chinese proverb: Man who try to pull wool over eyes wind up with sheep on face.
When Carvelli brings out his term papers, he says "Your category was social studies for $20. Hmmm, that sounds like a game show, don't it?" Juan later replies, "Sure! I'll take Paul Lynde to block!" This refers to the orignal version of The Hollywood Squares, which aired on NBC from 1966–81. This version included Paul Lynde in the center square, and contestants often used him to block.
