Goofs

The airplane on the ground at the airport in NYC is not the same plane shown flying in the air.

The tail fin number of the plane at start on the ground is N48WA, when it is shown flying the tail fin number is N711AG.

The business jet that the four fly to Paris is clearly an Eclipse or something similar, as the jet has wing-tip tanks, on the ground. When it cuts to the in-flight scene, it is clearly a Cessna or Bombardier business jet, missing the wing-tip tanks. After it has landed in Latham, it once again has the tip tanks.

When the police officer arrests the gang, he tells them they're breaking the Latham County Penal Code. However, when their case goes to trial, the District Attorney begins his argument by saying, "Ladies and Gentlemen, last year, our city council..."

When the prosecutors are preparing to try the group for breaking the Good Samaritan Law, the D.A. says that the main issue in the trial will be "character". Under the rules of evidence in criminal law, it is expressly forbidden for a prosecutor to initiate an attack on the defendant's character unless the defendant first attempts to offer evidence of good character.

The Massachusetts "Good Samaritan Law" does not mandate that aid be provided, but rather prohibits the recipient from suing the provider for any injury suffered.

The cop explains to the group that the Good Samaritan law required them to assist as long as it was reasonable to do. In this case it was not reasonable to do so as the perpetrator appeared to have a gun in his pocket pointed at the victim.

Though probably necessary for the purposes of the plot and dialogue, no American prison would house men and women in the same cell for extended periods of time, so in reality Elaine would have been imprisoned in a different location from the boys.

When their private jet entered a sharp dive, the people on board would have experienced a negative-G situation. Since George and Kramer were not wearing their seat belts, they would have been thrown to the ceiling of the cabin, not pinned to their seats.

While Jerry, George, Elaine, and Kramer are witnessing the robbery of the Massachusettian, the reflection of the police officer is visible in the store window just over Kramer's left shoulder. The officer is waiting for his cue to join the scene but has inadvertently already made his appearance; had his visibility been intentional, he too would have been guilty of breaking the Good Samaritan Law because he was idly watching the robbery.

In the shot where they get out of the cab in Latham and there's a close-up of the red car, it's clear there's no-one in it.

When the four of them are locked in the cell there is no latch visible to keep the door closed.

Marla (Jane Leeves) says it was October 1992 when she and Jerry (Jerry Seinfeld) dated but it was actually November.

The doctor testifies George's (Jason Alexander) reaction to the news of Susan's (Heidi Swedberg) death was "restrained jubilation". In episode 7.22 The Invitations (1996) however, his reaction was more surprised but indifferent.

Actually, George's reaction was more like "restrained jubilation," but there's still a problem: he didn't display that until the doctor left. So the doctor didn't witness that, and so he couldn't testify to it (even if someone told him about it later).

Wilhelm (Richard Herd) & Steinbrenner (Lee Bear) are seen talking amicably together in this episode despite Steinbrenner firing Wilhelm in episode 8.20, The Millennium (1997).

Elaine (Julia Louis-Dreyfus) says in this episode the Soup Nazi's soup isn't that good, but in episode 7.6 The Soup Nazi (1995), she loved it.
