In an industry best known for vanity and self-delusion, Kathy Griffin has a corner on humiliation. The comic returns for the second season of her slice-of-life series “Kathy Griffin: My Life on the D-List” (8 p.m., Bravo).

Viewers will be happy to know that her marital problems, chronicled last season, appear to have worked themselves out. In the process, she seems to have reduced her husband to the status of personal hairdresser.

In tonight’s episode, Griffin embarks on a “Red States” comedy tour and submits to the indignity of receiving the keys to the city of a small town and having only six people (all city employees) show up. To add insult to injury, the mayor opts to keep a dental appointment, so Griffin receives her keys from his assistant. She also endures the drama of an eBay charity auction and an on-air confrontation with Tyra Banks, who has frequently been the subject of Griffin’s mocking humor.

¢ On a similar theme, “The Janice Dickinson Modeling Agency” (9 p.m., Oxygen) follows the former “America’s Top Model” judge as she prepares to launch her own stable of runway stars. Despite Dickinson’s outsized personality, this show offers little we haven’t seen before. The over-the-top supermodel interacts with assistants and would-be models gathering at a crowded cattle call.

Can a woman who has spent the better part of the last four decades in front of a camera ever seem natural or spontaneous? In a moment purported to be intimate, she confesses her professional nervousness to her grade-school-age daughter. But the “just between us girls” nature of the scene seems completely undercut by the presence of a video crew.

¢ “Independent Lens” (9 p.m., PBS, check local listings) presents “The Great Pink Scare,” the true story of a Smith College professor who was fired from his job in the 1960s after police raided his house and discovered homoerotic magazines. The film explores the prevailing homophobia of the era, as well as contemporary fears about rights to privacy and efforts by authorities to regulate and monitor individuals and the books, magazines, films and Web sites they consume.
