After 18 years of waiting, Conan O'Brien finally invited parody master and Magic Box subject Weird Al Yankovic to be a guest on his show (not that he's been keeping track of time or anything). For his first appearance, the alabaster ginger prince hired the accomplished songwriter to craft some lyrics for his currently wordless theme song. When the big moment arrived, Al spared no feelings about getting the honor—albeit a little late—as well as no details about this one time the duo went camping. A diaper full of kittens, Coco? (The more you know.) Now if you're going to kill him, the least you could do is follow him on Twitter first.
