'The Walking Dead' Invades 'Conan' In Atlanta (VIDEO)

Merle and Carol of "The Walking Dead" invaded "Conan" while the TBS talk show filmed in Atlanta.

In a sketch from Conan O'Brien's late night show, Michael Rooker and Melissa McBride appeared as their "Walking Dead" characters Merle and Carol -- armed with guns and dirt -- and burst into the theater claiming that walkers (or "zombies" as O'Brien called them) were overrunning the street.

Their sanctuary didn't last long though: Andy Richter got shot up for telling a bad joke and Merle and Carol left to take their chances out on the streets-- with a special guest.

Watch the sketch below.

"Conan" airs weekdays at 11 p.m. ET on TBS.
