Sunday There are two reasons to watch the second-season premiere of "Hung" (9 p.m., HBO), which chronicles the further adventures of an All-American gigolo (Thomas Jane). One is the setting -- Detroit, a brilliant move since it's a city with a desperate need for Viagra. The other is Jane Adams, who plays his emotionally fragile pimp, a performance that deserves an Emmy nomination -- and a year's supply of Valium.

Monday Al Pacino did a killer job as Dr. Jack Kevorkian in the recent TV film "You Don't Know Jack," but the controversial doctor turns out to be a pretty dynamic personality even without the Oscar winner's acting chops. "Kevorkian" (8 p.m., HBO), a thought-provoking documentary from Matthew Galkin, gives its subject a chance to praise -- or hang -- himself, depending on what you think of his view on assisted suicide. Allowing viewers to make their own judgment is the mark of a brilliant documentary.

Tuesday "Louie" (10 p.m., FX) showcases the enormous talent of Louis C.K., whose previous TV effort, HBO's "Lucky Louie," was an unpolished gem. This effort is not nearly as adventurous, but it still provides a healthy dose of the comic's irreverent, what-the-hell take on the foibles of the world, especially in the wake of divorce and single parenthood. The language and situations are bawdy, even by basic-cable standards, but when it comes to C.K., who has written and directed every episode, we wouldn't want it any other way.

Wednesday MTV occasionally provides programs meant to benefit its teen audience. "The Real World" used to be one of them. No more. "The Real World: New Orleans" (9 p.m., MTV) is the most glaring example of how this groundbreaking series has become more about exploiting conflicts and less about bridging gaps. Yes, it's great for the Gulf Coast to have a TV show pouring in some money (and media attention), but the real reason the young people are in the Crescent City is evident from the very first episode, when the gang goes on a drinking spree that ends in a drunken display.

Thursday Jimmy Buffett takes a break from sipping margaritas to raise money for a worthy cause. "CMT Presents Jimmy Buffett & Friends: Live From the Gulf Coast" (7 p.m., CMT) is a live concert from Gulf Shores, Ala., focused on the oil spill that is ravaging the coast. Performers include Allen Toussaint, Kenny Chesney, Jesse Winchester and Sonny Landreth.
