- In general, any moment where George Fenneman is roped by Groucho into helping out with a stunt or demonstration.
- 1950-60: The "Stag Reels", shown at the sponsors' conventions and released in the Shout Factory DVD sets. There's a reason those bits didn't air.
- 1950s: Groucho asks a woman about her husband.
Woman: Oh boy, have you ever been made love to by a Frenchman?Groucho (flustered): Not...not that I can recall!
- 1956-57: The Secret Word Duck once landed directly on George Fenneman's head, a moment that went into several of the aforementioned Stag Reels.
- October 16, 1958: Rowena Heimstra, a.k.a. "Crazy Legs" Rowena, demonstrates a dance which lives up to her nickname. Words could not do it justice. It made enough of a sensation that she was brought back on the May 21, 1959 show just to do that dance.
- April 21, 1960: "Crazy Legs" Rowena had a Spear Counterpart in the form of Glenn Turnbull, who demonstrated a "legs-mania" dance to the song "Ballin' the Jack" which was just as great as Rowena's moves. The goofy expression he puts on at the end is the icing on the cake. Watch him in action (the dance starts at 15:05).
- According to some retellings of the "cigar incident" urban legend, the uproarious laughter in response to Groucho's infamous line was recorded and used by NBC for years whenever they needed an appropriate reaction to any "very hilarious" joke.
- From the Cosby era, a woman confuses Bill from North, South Carolina and back.
