The Walking Dead's Jeffrey Dean Morgan Sings Happy Birthday

This season in the "Sing Me A Song" episode of The Walking Dead, after Carl infiltrated The Sanctuary and gunned down two Saviors, Negan punished the "little serial killer in the making" by having him sing a song. When Carl — who was clearly flustered by the request — didn't break into song right away, a stern Negan pointed Lucille in his face. That was all the motivation the one-eyed lad needed to get him croaking out a haunting rendition of "You Are My Sunshine."

Earlier this month, while appearing on Popcorn with Peter Travers, the show's host asked Jeffrey Dean Morgan to sing, and the 50-year-old actor appeared just as uncomfortable by the request as Carl did. And just like Negan did with Carl, Travers told Morgan he could sing whatever song he wanted to, but "Happy Birthday" was the only song that came to his mind.

Check out Morgan's vocal skills in the video above.
