55. Dr. Reston
Best-known episode: "The Watch"
Among the least comforting therapists in TV history, Dr. Reston embodied everyone's mental picture of a super-intense shrink: gravelly voice, intimidating intellect, smirking face, a fascination with our humiliating hang-ups. ("Elaine, have you been urinating a lot again?") It's telling that in Seinfeld's world of overgrown adolescents, he seemed like an actual adult — a mean one who bullied Elaine with his superior mind and manipulated Kramer into befriending him. No wonder our heroes never wanted to grow up. TIM GRIERSON
