Trivia: Julia Louis-Dreyfus was pregnant during the filming of season 3 and then again in season 8, this was hidden with oversized clothing and bags.
Trivia: The Voice of George Steinbrenner on the show is co-creator Larry David.
Trivia: In every episode of Seinfeld there is a Superman reference somewhere.
Suggested correction: This is a myth and not true. Even if you count seeing the Superman fridge magnet or Superman statue as a reference, they didn't appear until season 4 and 5.
Season one had a few and one of them is episode 15 The Stock Tip. To quote George: "I never heard him say anything really funny." Jerry: "It's common sense. He's got super strength, super-speed; I'm sure he's got super-humor." "Either you're born with a sense of humor or you're not. It's not going to change. Even if you go from the red sun of Krypton all the way to the yellow sun of the Earth."
That wasn't the point of my correction. The trivia is wrong because not EVERY episode has a reference. I didn't say no episode prior to season 4 or 5 had a Superman reference. I only said the magnet and statue didn't appear until season 4 and 5, so even if you want to count those objects as a Superman reference, it doesn't apply to season 1-3.
Trivia: The Parking Garage was originally written to end with Kramer driving around the mall, but the actual car wouldn't start, so they went with that ending.
Trivia: Helen Slater (Jerry's interest in this episode) played the lead in The Movie Supergirl. Jerry is a huge Superman fan.
Trivia: When Kramer is in The Soup shop talking to The Soup Nazi there is a black board on the wall that has all the soups on it. If you look closely Mulligatawny (Kramer's soup), Crab Bisque (Jerry's soup), Turkey Chili (George's soup), and Jambalaya (Newman's soup) are all in order.
Trivia: Jason Alexander was always fitted with an outfit that was one size too small. This was done to make George look "uncool." On the flip side of the coin, Michael Richards was always fitted with an outfit that was one size too big, to make Kramer appear loose and lanky.
The Masseuse - S5-E9
Trivia: One of the subplots concerned Elaine's new boyfriend, "Joel Rifkin". Within the episode, Elaine wanted her boyfriend to change his name because he shared the same name as the serial killer named Joel Rifkin who had been arrested June '93. She has a conversation with her boyfriend, Joel, and suggests he change his name to the less scary Dion, Ned, Remy and then O.J. The show aired in November, 1993, seven months before football Hall of Famer O.J. Simpson would be tried for the murders of Nicole Brown Simpson and Ron Goldman.
Trivia: Larry David, creator of Seinfeld, is the B-movie actor who yells something Jerry writes down, but later he can't read his own writing.
The Pool Guy - S7-E8
