Conan O'Brien's weeklong visit to Atlanta wouldn't be complete without a crossover with AMC's hit adaptation of The Walking Dead, which calls the city home.

The opening monologue of last night's Conan was interrupted by a frantic Merle Dixon and Carol Peletier (played by Michael Rooker and Melissa McBride), seeking protection from the herd of walkers outside (not zombies, as Merle noted to the talk-show host).

"Please, please, we're good people," Carol pleads, clearly not speaking for the elder Dixon brother. Soon, however, they discover what's inside Atlanta's Tabernacle may be worse than what lurks outside.
