Frasier (season 6)

After several acts of kindness backfire, Frasier starts to lose his faith in humanity. Driving home in the rain, he comes across a stranded woman and considers whether or not to give her a ride. Despite the events of the day, he decides to help her, only to discover that she is a prostitute (and also a transvestite), and that the police are watching everything. He is arrested and held at Martin's old precinct, where Martin and Niles must bail him out. Upon returning home and explaining the situation, his son Frederick asks; "So are you saying you shouldn't help people?" The scene returns to Frasier in the car contemplating whether or not to give the woman a ride (the preceding events having been what Frasier later describes as a 'bad daydream'). Despite knowing that this good deed, like all the others, may backfire he still decides to help her.

Roz's mother Joanna is visiting, and Frasier suggests fixing her up with Martin. They spend an evening together, but after Roz and Joanna have left, Martin admits to Frasier that he found her very boring company. Roz, though, reports that her mother had a wonderful evening and hopes to see Martin again before she leaves Seattle.

Frasier receives a phonecall during his show at KACL from Woody Boyd (Woody Harrelson), an old friend from Cheers, who has just arrived in Seattle for the week. They catch up, but Frasier soon finds that he is no longer enjoying spending time with Woody, since they have nothing in common except a few old stories. He also feels bad for him as Woody is still a bartender while he is a famous psychiatrist. However, he cannot bring himself to hurt his friend's feelings. When Woody leaves town early, Frasier bids him farewell, then goes out with Niles for a late supper to celebrate. Once at the cantina, he spots Woody hiding behind a menu at the bar. Woody explains that he feels sorry for Frasier, as he still lives with his father and goes out with his brother. Frasier realizes that Woody does have a good life that keeps him happy, and tells him how lucky he is. They agree to share a last beer and promise to reconnect in five or ten years.

Frasier is in Café Nervosa interviewing candidates for a new radio psychiatrist at KACL, whose show will run alongside his own. He thinks he has found an unbeatable contender (Dr. Gordon Edelstein), and Niles, who knows his work, expects him to be right. In the end, however, he recommends Dr. Nora Fairchild, who spends most of her interview paying him compliments, even pretending to think Niles is the older brother. Frasier feels proud to have a protégé, until he actually hears her in action. She turns out to be an advocate of old-fashioned values, condemning pre-marital sex, divorce, single parenthood and the like, and her approach to therapy is not so much constructive criticism as outright abuse. Frasier is embarrassed and angry and withdraws his recommendation, however it turns out that this is no longer a factor; Dr. Nora attracts so much attention (positive and negative) that Kenny wants to keep her on and decides to make her a permanent fixture. When she openly criticises Frasier's advice to one particular caller on air and makes clear her intention to undermine and embarrass him at every opportunity, he and Roz decide on a declaration of war. Roz is able to find proof that Nora is a hypocrite and doesn't even have a medical degree of any kind- she is a gym teacher instead, but Frasier has second thoughts about stooping to Nora's level. Fortunately, Niles has been listening to this caller and the way Dr. Nora dealt with her, and he has a more subtle way of approaching the problem: find her mother and use her to find the problems with Nora's abusive approach. That turned out to be a terrible idea as she reveals herself to be much, much worse than Nora, abusing her on the air and causing Nora to scream and cry bloody murder out of KACL with her monstrous mother in pursuit, with it heavily implied to have happened dozens of times before.
