The Robbery - S1-E2
Trivia: Michael Richards invented his patented Kramer entrance in this episode on accident. He missed his cue and thought he would make up for lost time.
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: 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.
Trivia: In this episode, Kramer was supposedly carrying an air conditioner in an awkward-shaped box. To make it more realistic, actor Michael Richards actually did carry around an air conditioner for the entire episode.
The Masseuse - S5-E9
Trivia: One of the subplots concerned Elaine's new boyfriend, "Joel Rifkin".

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.
