Dexter is a pretty amazing show. A serial killer who kills other serial killers is a character I can really get behind. Michael C. Hall does a great job with this character, but who knew he was a serial killer with some serious vocal talent? Michael C. Hall was on Late Night with Jimmy Fallon the other night, and when Jimmy asked him what Dexter’s favorite Christmas song would be, it didn’t take him long to come up with Santa Claus is Coming to Town. He broke into an excellent rendition, and changed the lyrics to make it appropriately creepy for the character he portrays. Who knew that Dexter songspoke?
