The second half of The Walking Dead's (pretty excellent) season 4 begins on this Sunday evening, but last night talk show host Conan O'Brien welcomed the show back with a full-on undead extravaganza, complete with zombie lesbians making out, Daryl singing, and the greatest cold open in Conan history.

The cold open is obviously above, so here's an extremely weird duet between Daryl and Carol of an original song which will haunt my dreams forever:

And last but not least, sexy zombie-girl-on-zombie-girl action.

As for the rest of the interviews, which featured Danai Gurira (Michonne), Steve Yeun (Glenn) and Lauren Cohan (Maggie), in addition to Norman Reedus and Melissa McBride, there are two clips so far, featured here.
