Factual error: In the scene where Anna is standing with George beside his father's GTO, Elaine suddenly runs in and pries her away from George. Elaine and Anna get into the cab. As the cab pulls away, the side door is marked as an NYC cab with a taxi license number, etc., but the license plate in the back is a California plate.
Factual error: The grocery store that Kramer walks into with Little Jerry has a round doorknob. Those were phased out of public use in 1992 after the Americans with Disabilities Act took effect, but this episode takes place in 1997. (00:09:45)
Factual error: On the bottom of all checks, they have the routing number, followed by the account number, followed by a repeat of the check number found in the top right corner. When we see Jerry's bounced check, "1246" isn't seen after the account number.
Chosen answer: George does mention his brother in the episode "The Parking Space". They actually really never mention anything that contradicts the fact he had a brother though, it just isn't mentioned.
