OK, just recently saw "The Stranded" and in it, George's friend from work is at a party on Long Island. When George walks in, the friend says:
"Guess who just sold 129 West 81st?"
well, guess what! That's supposed to be JERRY'S address on the show. I guess the show was written before they decided what his address was going to be and so they just used larry david's (or jerry's) old address.
hee hee... neat ay?
