Hopefully, you'll be too busy hitting the streets to watch anything tonight, but with Oprah in primetime you'll have 30 minutes to rest before taking it to the man again. WATCH 30 Rock [9:30 PM, NBC] - Liz (Tina Fey) hassles divinity-star Oprah for personal advice on a trip back from Chicago. Jenna (Jane Krakowski) and Tracy (Tracy Morgan) trade places to see whose life is worse. Kenneth (Jack McBrayer) puts Jack's (Alec Baldwin) value system to the test. Our expectations for Obama are pretty high, but that's nothing compared to our dreams for this episode. Help us, Liz Lemon! You're Ben Silverman's only hope!

50 Cent: The Money and the Power [10 PM, MTV] - Fourteen contestants are broken up into teams, bound together and then told to run five miles through Brooklyn. The winner on 50's show gets a $100,000 business investment. Instead of a record label, clothing line or production company, we would like the winner to open a store that sells exhaust fans called "Straight Hood." TiVo Man-Made [9 PM, National Geographic] - Scan through this week's episode that features 1 Bryant Park's ambitiously green skyscraper. It's a good bit of trivia for that New York conference call.

Celebrity Rehab with Dr. Drew [10 PM, VH1] - The patients start talking about their feelings. Learn that Rodney King feels bad about being an absentee father, Sean Stewart is still reeling from growing up with an absentee father and Tawny Kitaen dumped her real name, Julie. The group struggles to understand why Gary Busey refuses to admit he has an addiction problem. We are completely open about our Busey-dependence problem. KILL Grey's Anatomy [9 PM, ABC] - The producers of this show obviously got caught up in the Pro-Prop 8 fever: We're skipping Grey's after news that our favorite medical-interest lesbian couple is being ripped apart. Why couldn't they have just referred to Dr. Hahn as Callie's "friend" and left it at that? That's how the Midwest handles such stuff; this is how we roll in Los Angeles.

Eleventh Hour [10 PM, CBS] - Tonight the gang travels to somewhere in Pennsylvania and attempts to contain a lethal virus that causes television executives to prefer serious science-based dramas over life-affirming fare that makes us forget that there might not be a point to all of this mortal toiling.
