Jerry Seinfeld credits the phrase, "These pretzels are making me thirsty," from the episode "The Alternate Side" as the first of the show's many catch-phrases. During his next stand-up tour, audience members would chant this during virtually every performance.
According to Jerry Seinfeld, this is his least favorite episode of the series. Seinfeld was uncomfortable with the scenes involving Owen (Edward Penn).
George wears a jersey with "Broadway Bound" on it in the first scene. Jason Alexander played Stanley in the original Broadway cast of Neil Simon's play "Broadway Bound."
