If you’ve ever wondered how Conan O’Brien came to be the renowned talk show host that he is (besides the oft-documented story of working on The Simpsons then replacing Letterman at Late Night), then watch his “official” origin story that he presented at his second day at Comic-Con. 

Also, in the same day, Conan ran into a bit of problem with a very surprising appearance by Chris Parnell apparently cosplaying as Game of Thrones author George RR Martin who had a very surprising book cover on the books the was signing.

Having already done zombie bits with a Walking Dead episode of Conan in the past, we can’t imagine what he’s going to pull on tonight’s episode with the cast of the Walking Dead.
