What's On: 24's Real Eleventh Hour

It's a tough night for fans of the two most dependable dramas of the decade, as 24 and Law & Order end their incredible runs this evening. We've buoyed those rather somber viewing options with lighthearted fare in case you're not in the mood to close up your Kiefer Sutherland/Sam Waterston-themed hope chests just yet. Look: Frenchie's leaving beauty school!

24 [Fox, 8 PM]

Jack Bauer reminds us one last time that he's handy with firearms and frosty glances in the series finale of this terrorism-terrorizin' saga; President Taylor continues to gun for the peace treaty, and the most unsmiling television actor in history, Eriq La Salle, makes an appearance as the UN Secretary General. Farewell, Jack Bauer. You've protected us, scared us, thrilled us, and comforted us -- mostly because you still look like the blond bully in Stand by Me.

Dancing with the Stars [ABC, 8 PM]

In the final week of performances, the remaining celebrities tackle "redemption dances." This means Evan Lysacek can finally perfect his Viennese Johnny Weir Snub, Erin Andrews can nail down her Obsessive Perfectionism, and Nicole Scherzinger can drink a Vitamin Water and chill out, because she hasn't messed up yet.

Law & Order [NBC, 10 PM]

Good God, can TV get any more emotional tonight? Law & Order's series finale ends the 20-year-old series with a case regarding a blogger that brings Van Buren's personal issues to the public's attention. The final guest star is Olympic champion Lindsay Vonn, which is weird but fine. I'm practicing my approving Orbachian nod for the final scene.

Grease [AMC, 8 PM]

Screen duo John Travolta and Olivia Newton John would later give us the perfect film Two of a Kind, but they start off modestly here as two "Summer Lovin'" kids in high school. The film did OK: It's the highest-grossing musical of all time domestically, one of the top five grossing films of the 70's, and legally the last time Stockard Channing could play a high-schooler (at age 33).
