Amazing he found a way to go on for 10 1/2 minutes... and to an R&B beat too.
That is what makes the vid even more amusing to me. I respect R&B, but a lot of the beats seem generic and get repetative. I know that if you were to put me on an R&B beat I wouldn't be able to go for more thirty seconds.
But then, you have Weird Al, who can find a way to make anything work to his ideas musically. In the world of parody the guy's a genious.
