The new season of Jerry Seinefeld’s “Comedians in Cars Getting Coffee” has launched. Sarah Jessica Parker and Jerry drive a faux wooden panelled Country Squire station wagon out to East Meadow, Long Island, which is not the Hamptons, by the way. We learn that Jerry’s parents never smiled at him, and that he over tips. SJP seems to go for 18%. “I’m glad I’m not married to you,” she says when they negotiate at a coffee shop. We also learn that SJP and her siblings sang back on a Harry Chapin one week before he died in 1978.
