* THE NEWSROOM. 9 p.m. Sunday, HBO.
Jane Fonda returns for the series finale, which encapsulates both what's infuriated and what's entertained me over three seasons. Aaron Sorkin may never figure out what women want or why his ventures into gender politics so often offend, and we may never figure out why the Internet scares him so much. But he knows how to create heart-tugging moments with words and music and how to deliver a happy ending (even if you're one of the people who's not happy it's ending).
* THE COMEBACK. 10:05 p.m. Sunday, HBO.
A good review, an encounter with an emotional former colleague and a prolonged desert shoot with snakes make for an emotional day for Valerie (Lisa Kudrow). This show gets deeper and funnier by the week.
* UNDERCOVER BOSS. 8 p.m. Sunday, CBS3.
An ex-FBI agent who's now CEO of True Value hardware sports a long graying wig and a mustache to fool his employees in the Season 6 premiere.
