Bryan Cranston Plays Tim Whatley

Tim Whatley

Bryan Cranston appeared on Seinfeld as Tim Whatley, Jerry and Kramer's unorthodox dentist. He was first introduced in season 6, episode 8, "The Mom and Pop Store," when he invited Elaine to a party at his house and left Jerry questioning whether he was also invited or not. Tim was as charming as he was cocky, and his personality often mixed with his unusual dentist practices. In one episode, it's suggested that Tim had sex with his assistant while Jerry was unconscious during a tooth filling. "Is this guy a dentist of Caligula?" Jerry asked Elaine.

Bryan Cranston was a forgotten Seinfeld guest star, but he made some important appearances on the show. Jerry didn't necessarily like Tim, but he was often drawn by the dentist's unusual persona, which prompted him to get to know him better. Tim continued to appear sporadically until the final season. He was known by Jerry and his friends as a re-gifter — someone who gifts people presents that were previously gifted to them. Tim also went through a hilarious arc in Seinfeld season 8, episode 19, "Yada Yada Yada," when he suddenly decided to convert to Judaism, while Jerry believed it was just a ruse.
