The Walking Dead star shared this photo on Facebook, writing "I photo bombed." No kidding! He ended up conquering this photo of Game of Thrones stars Lena Headey (Cersei) and Peter Dinklage (Tyrion) with fans at the Calgary Comic & Entertainment Expo.
To be photobombed by Daryl Dixon is a blessing, and obviously Norman was just joking around, not being disrespectful. He's a GoT fan, as well as a goofball, and should probably reenact this exact pose for every TV show.
In a slightly related note, check out Lena's ring. How cool is that?
