George played Frogger in HIGH SCHOOL???
Jason Alexander was born in 1959, Jerry Seinfeld (the person not the character) was born in 1955. Video games didn't really become popular until the 1980's (although Space Invaders came out in 1978, Frogger came out later). George and Jerry were supposed to have been friends in high school, the implication being they were the same age (usually students in different grades do not have gym class together) Just how many years younger is George than Jason? And how many years younger than Seinfeld (in real life) is Seinfeld (the character)?
It would seem Jerry is shaving at least eight years off his real-life age. If he was 18 in 1981 (oldest age in high school, earliest time Frogger would have been available) his character must have been born in 1963.
