TONIGHT'S MUST-SEE

"Unforgettable Moments in Television Entertainment," 7:30 p.m., NBC. TV has had plenty of moments that burned into the national consciousness. This show might only be able to skim by them — since it's including only 70 moments in 90 minutes, counting commercials — but it should still be fun. Larry Hagman will be on the show, with the famous "Dallas" episode asking "Who shot J.R.?" Jason Alexander will be there with the infamous "Seinfeld" episode "The Contest." And Bob Newhart will be there with the twist to his show's finale. There's more, both humorous (Lucy stomping grapes in "I Love Lucy") and sensuous (David Caruso and Amy Brenneman in the first "NYPD Blue" love scene). There's more comedy, from Sammy Davis on "All in the Family" to the "Friends" finale; there's music, from the Beatles on "The Ed Sullivan Show" to "American Idol." The show, supervised by the Museum of Television and Radio, also includes Michael Chiklis, Shelley Long, Doris Roberts, Cybill Shepherd and Donald Trump.

OF NOTE

"Brat Camp," 7 and 8 p.m., ABC. First is a rerun, with the teens each spending three days in the wilderness. Then in a new hour, they talk about what went wrong before they were sent to this tough-love, wilderness-survival program.

"So You Think You Can Dance," 7 p.m., Fox. The field is trimmed from 26 to 16.

"Over There," 7 p.m., FX. In the third episode of this intense Iraq war series, the soldiers have doubts about a colonel's interrogation methods, used on a prisoner captured while trying to slip through an Iraq roadblock by hiding in a car trunk. Meanwhile, against doctor's orders, the hospitalized Bo insists on being taken off morphine. His wife helps him get through the pain and withdrawal.

"Rock Star: INXS," 8 p.m., CBS. Yet another reality show. It's time to trim a sixth contestant.

"Lost," 9 p.m., ABC. This excellent rerun focuses on Michael (Harold Perrineau Jr.) and his bumbling attempts to get along with his son Walt (Malcolm David Kelley).
