TIM WHATLEY

'Dr. Tim Whatley' is a fictional character on the American sitcom ''Seinfeld''. He is played by Bryan Cranston (''Malcolm in The Middle'').
Nicknamed "Dentist to the Stars", Whatley is a recurring character, and appears as Jerry's dentist.
In "The Yada Yada," Whatley converts to Judaism, and Jerry expresses to Whatley's Catholic priest in a confession his belief that Whatley has done this solely for right to make jokes (which offends him, not as a Jewish person, but as a comedian). Also in this episode, Kramer coins the phrase "anti-dentite."
Whatley briefly dates Elaine.
Whatley was branded as a "re-gifter" in the episode "The Label Maker," when he gives a label maker to Jerry as a gift because Jerry gave him Super Bowl tickets, when Elaine realizes that it's the same label maker Elaine had given to him as a gift for not charging her for dental work.
In "The Jimmy," Whatley irks Jerry by having ''Penthouse'' magazines in his waiting room and by possibly 'violating' him while he was unconscious during a tooth filling.
