I had forgotten just how packed with comedy the episode "The Pick" was!
This one episode had: Elaine's Christmas card that exposed her, George trying to get back with susan only to feel immediately doomed when he succeeded, Jerry spied "scratching" his nose by Tia, the model he met on the plane, Kramer confronting Calvin Klein on the theft of his cologne idea, only to get a modeling job ("spectacular buttocks!").
Every scene was great! I think this density of comedy is what we miss in current episodes.
