It's a Lock: How Can Sanjaya Lose With Hair Like That?

"Dancing With the Stars." Dance competition's latest-edition debut, featuring highly promotable, one-legged, cause-y former Beatle's estranged wife, cops ABC's largest Monday 8 p.m. audience -- nearly 22 million viewers -- in more than 15 years.

"Planet Earth." The first three hours of Discovery's lush documentary clocked nearly 6 million viewers Sunday night -- the network's biggest haul since its docudrama "The Flight That Fought Back" in November '05. Discovery says 12 million people sampled at least a minute of the program, which was more than five years in the making.

"Bring It On: All or Nothing." Nearly 5 million people caught the cable TV premiere of the second direct-to-video sequel in the (gak) "Bring It On" high school cheerleading saga. It was ABC Family's most watched movie premiere ever and the week's No. 1 basic cable flick. Sunday from 8 to 10, nearly 11 million people were watching Discovery or ABC Family.

"American Idol." Fox has already snagged first place for the season among the 18-to-49-year-olds advertisers crave thanks to "Idol," which logged 30 million viewers on last Tuesday's performance night and 27 mil on Wednesday's advertising, er, results night. Last year, Fox didn't take the demographic crown until the final night of the TV season, which also happened to be the night Prince performed on the "Idol" finale.

" 'Til Death." Minutes after Brad Garrett camped it up onstage with the Idolettes, his sitcom copped nearly 15 million viewers on Fox -- the network's biggest sitcom haul in more than three years and the biggest sitcom draw on any network so far this season.

Miss USA. Even the lure of seeing outgoing Miss USA Tara Conner post-rehab couldn't keep Donald Trump's chick pageant from falling to its smallest audience on record, 7.4 million viewers.

"Six Degrees." ABC's returning serialized drama scored just 4.5 million viewers Friday after a "Grey's Anatomy" rerun. That's about 2 million fewer than the network posted in the slot last month with mostly newsmags.

"Grease: You're the One That I Want." Nearly 7 million watched the wrap-up episode of NBC's singing/dancing competition. That was its best performance since late January, but it came nowhere close to the debut audience of 11.5 million.

The week's 10 most watched programs, in order, were: Fox's Tuesday and Wednesday "American Idol"; ABC's Thursday "Grey's Anatomy" and "Dancing With the Stars" debut; CBS's "CSI: Miami," "NCIS" and "Criminal Minds"; Fox's " 'Til Death"; NBC's Monday "Deal or No Deal"; and CBS's "Cold Case."
