TONIGHT'S MUST-SEE

"Knights of Prosperity" return, 7:30 and 8:30 p.m., ABC. Last fall, ABC introduced a line-up stuffed with complex shows. Most failed; now some get to play off their leftover episodes. The gang has given up on robbing Mick Jagger and is into new schemes. First, it needs seed money; the plan is to pretend to kidnap Louis the intern, then get a ransom. Meanwhile, the plot shifts to Ray Romano (who plays himself). The gang will steal a diamond ring from his safe — if he ever leaves the apartment.

"So You Think You Can Dance" (7 p.m., Fox) and "Last Comic Standing" (8 p.m., NBC). In scheduling overkill, two of the best competition reality shows used to overlap. Now "Dance" — down to six terrific, young dancers — has trimmed back to an hour. That lets us also catch "Comic." Tonight, the eight remaining stand-up comedians entertain at a medieval tournament.

OF NOTE

World Music Awards, 7 p.m., MyNetwork (KFVE). This is a rerun, with Lindsay Lohan hosting and music by Beyonce, Nelly Furtado, Michael Jackson, Rihanna and Andrea Bocelli.

"According to Jim," 7 and 8 p.m., ABC. In the first rerun, the anniversary plans for Jim and Cheryl are detoured when her sister Dana goes into labor. In the second, Jim wants to find someone to take Cheryl to musicals, so he doesn't have to.

"Rescue Me," 7 and 9 p.m., FX. Janet rages at Tommy after her baby disappears. Meanwhile, Franco is having second thoughts. Alicia returned, just after he proposed to Natalie.

"Power of 10," 7 p.m., CBS. Here's the second round of this fun game show, amiably hosted by Drew Carey. Contestants simply guess how people responded to a poll.

"The Nine," 9 p.m., ABC. Here's another complex ABC show, getting to air its final new episodes. There are new complications for the former bank hostages: They have learned about the relationship between Jeremy (Scott Wolf) and Franny (Camille Guaty). Also, Jeremy's former girlfriend Lizzie (Jessica Collins) has disappeared.

"Real World" season opener, 10 and 10:30 p.m., MTV. The original reality show is back, this time in Sydney, Australia.
