Tony's romance with Gloria Trillo really heats up--they even make whoopee at the zoo. But A.J. gives Tony no pleasure; he gets into big trouble at school. Meanwhile, Jackie Jr. starts to follow in his late father's criminal footsteps. And when Tony starts to think bad thoughts about you, it's maybe not so good for your health. Stars James Gandolfini, Robert Iler, Annabella Sciorra, and Dominic Chianese.
