One of my pet peeves is that sometimes the talents of my band get overlooked because, and it was the same problem that Frank Zappa had, with a lot of groups that use humor, people don't realize there's a lot of craft behind the comedy.
I suppose I had my rock star fantasies while I was singing into my hairbrush in the bathroom mirror, but I never really consciously said, 'OK, this is what I'm going to do for a living and I'm going to be Weird Al.'
I make charts of songs that are good candidates, good targets, so to speak. Then I try to come up with ideas for parodies. And 99% of those ideas are horrible.
