Character: weird al yankovic
Alfred Matthew "Weird Al" Yankovic is an American song-maker best known for his parodies, though he is also a talented composer. He has released 12 Albums since 1983. He is also, possibly, the most awesome guy ever. Just sayin'.
That said, there are a whole lot of songs that were NOT actually written by him, but are credited to him anyway. If you're not positive, google a bit and make sure. Of course, how often are you really going to be posting Weird Al here? This is e621! Geeze.
