TBS has announced that Conan O’Brien will host an 11 p.m. talk show on the network, expected to debut in November 2010. George Lopez, whose Lopez Tonight will move back to midnight, was instrumental in the deal — TBS began talks in earnest with O’Brien just last week, after Lopez personally called Conan and asked him to consider joining the late-night lineup. “In three months I’ve gone from network television to Twitter to performing live in theaters, and now I’m headed to basic cable. My plan is working perfectly,” O’Brien said in a statement. (Admit it: You thought he was just joking on Twitter today when he wrote, “The good news: I will be doing a show on TBS starting in November! The bad news: I’ll be playing Rudy on the all new Cosby Show.” I did.)

While you start to ponder how far he can push the envelope at 11 p.m. on TBS and how funny it is that he will once again cause NBC affiliates to lose viewers for their local news telecasts, we also need to discuss (gulp) how you’ll deal with the Daily Show/Colbert Report/Letterman/Conan traffic jam. (Theoretically, you could DVR Conan and The Daily Show at 11 p.m., Letterman at 11:30 p.m., and The Colbert Report repeat at 2 a.m. — but that’s a late night.) And as for the question in our headline, where does the new Team Coco/Lopez stand on your list of favorite late-night tandem?
