TONIGHT'S MUST-SEE

"Last Comic Standing," 8 p.m., NBC. Last week, Michele Balan was cut, leaving three men to perform. Josh Blue, from St. Paul, Minn., had a terrific stand-up set as usual. He again managed to have it both ways — overcoming his cerebral palsy yet using it for laughs at just the right moments. Ty Barnett, from Chicago, had a fairly good set. Chris Porter, from Kansas City, had an eccentric one. In order to work well, it needed viewers to have seen a specific commercial. Tonight, one will be eliminated and the other two will perform. Then viewers can vote. The champion — to be announced tomorrow — gets an NBC deal and a special on cable's Bravo.

"Rescue Me," 7 p.m., FX. Last week ended with a jolt: Janet, the ex-wife of Tommy and the girlfriend of his brother Johnny, is pregnant. What Johnny doesn't know is that either brother could be the father. Tonight, there are some messy confrontations. Meanwhile, Franco is having troubles with his girlfriend's blunt brother. And Uncle Teddy feels conjugal visits aren't much fun.

OF NOTE

"Eureka," 6 p.m., Sci Fi Channel. Strange things keep happening in a town stuffed with scientific geniuses. Spencer, Henry's young assistant at the garage, hosts a movie party; it gets so wild that Jo, the deputy, investigates. The next morning, Spencer claims he was abducted by aliens and Jo plots to kidnap the congressman who supervises Eureka's funding.

"Fear Factor," 7 p.m., NBC. It's a generational battle with two teams of people in their 20s and people twice their age. The skills involved? Women are placed in a pit filled with 10,000 hissing cockroaches. Guys must eat their way through cow or pig intestines.

"House," 7 p.m., Fox. A young woman says she swallowed a bottle of sleeping pills because she hadn't slept in 10 days. Dr. House has his own sleeping problems. He's been disrupted by sharing his apartment with Wilson.

"According to Jim," 7 p.m., ABC. After dumping its reality show "The One," ABC has lots of space to fill on Tuesdays and Wednesdays. It starts tonight with a rerun that has Jim crying during a movie — and his wife finding no charm in that.

"Bones," 8 p.m., Fox. Somebody shoots at Brennan. She's sure that's tied to one of two cases she's working on — but which one?

"Boston Legal," 9 p.m., ABC. Daniel Post (Michael J. Fox) volunteers to help Denise with her harassment case. Shore is way to busy, working on a case and on Crane's wedding.

"Law & Order: Special Victims Unit," 9 p.m., NBC. Was a woman killed because of her day job as a lawyer or because of her night job as a stripper?
