The King of Queens - Season 4 Episode 24
Two Thirty

In the first half-hour, Doug believes that his new dentist --who once had a crush on Carrie--is hurting him on purpose. The second story, which marks the shows 100th episode, focuses on Carries dad, Arthur. When Arthurs volatile behavior gets out of control, Doug and Carrie insist he visit a psychiatrist. During the session, Arthur recalls via flashback a disturbing encounter with his own disgruntled dad that may be at the root of his abrasive personality.
