What’s new on the idiot box tonight:

NCIS: Los Angeles (CBS) Crossover Event Pt. 2: Other than both being cop shows on CBS, is there any real reason to crossover Hawaii Five-O and NCIS: Los Angeles? Why not, say, Criminal Minds and 2 Broke Girls? ---Anyway, in tonight’s thrilling conclusion, the miracle of HD allows the ginormous heads of Scott Caan, Chris O’Donnell and LL Cool J to occupy the same television screen at once.

The Secrets of Bin Laden’s Lair (Discovery) Or at least the secrets the U.S. military will allow—but come on, any show with “lair” in the title is worth watching.

Also new tonight:
Last Man Standing, Cougar Town, Dancing With the Stars, Private Practice (ABC); The Biggest Loser, The Voice, Fashion Star (NBC); Glee, New Girl (Fox); 90210, The L.A. Complex (The CW); 16 & Pregnant, Savage U (MTV); The Little Couple (TLC); The Real Housewives of Orange County (Bravo); Chopped (Food Network); Guiliana & Bill (Style); Dance Moms: Miami, Love For Sail (Lifetime); The Deadliest Catch (Discovery); Shannen Says (We); Fact or Faked, Dream Machines (Syfy)
