The audience response to the end of George's (Jason Alexander) story is regarded by many as one of the longest sustained laughs by the "Seinfeld" studio audience in the show's history, rivaled only by the response to Kramer's (Michael Richards) line "I'm out" from Season 4's The Contest (1992).
In an interview, Jerry Seinfeld declared George's (Jason Alexander) ending monologue the funniest moment of the entire series, saying, "The hardest thing in comedy is to have the biggest laugh at the end, and it's the most satisfying thing."
In the scene where Elaine (Julia Louis-Dreyfus) complains to Kramer (Michael Richards) about her pocket organizer, you can see a "glamour" photo of Jerry (Jerry Seinfeld) on Kramer's wall. This photo is also visible in "The Conversion."
George's (Jason Alexander) final monologue was not in the original script. Larry David came up with the idea while the episode was being filmed; it was added as a result of a late-night rewrite the night before shooting and no time to rehearse was available. Alexander quickly memorized the monologue so rehearsal wasn't necessary. It's rumored that only one take was filmed, but Elaine's hand is not against her head right after George says, "Easy big fella!" then they immediately cut to another camera angle and her hand is against her head. So they filmed at least two takes.
You can also see Julia Louis-Dreyfus trying not to laugh after Alexander says, "Easy big fella." This is probably why they had to do a second take because Dreyfus was known to break into laughter quite a bit during shootings.
