Jerry Seinfeld is back with a new season of his web series, “Comedians In Cars Getting Coffee,” and his first guest is Sarah Jessica Parker. While we never had a station wagon like the one in this episode, at least two of my friends’ families did, so this brought back a lot of memories and some wonderful observations about what life was like for those of us who grew up on Long Island in the 1960s and 1970s, including an egg cream made with Fox’s U-Bet chocolate syrup.
