"Serenity now" are the control words that George's dad, Frank (Jerry Stiller), is supposed to utter every time his blood pressure rises. Conversely, Jerry (Jerry Seinfeld) finally learns how to lose his temper -- and it isn't pretty. In other developments George (Jason Alexander) is invited to join Frank's latest business enterprise, selling computers -- bringing him in very close contact with his old enemy Lloyd Braun (Matt McCoy). Elaine (Julia Louis-Dreyfus) discovers her "shiksappeal" when a young Jewish boy tongue-kisses her during his bar mitzvah. And Kramer (Michael Richards) takes on "Anytown, U.S.A." ~ Hal Erickson, Rovi
