In fact, when I come up with an idea for a parody I try to resist the urge to Google the idea to see if someone has done it already because the answer is almost always, "Yes, of course they have, they've thought of it!"
My own personal tastes don't really have an effect on whether song is a parody target or not. But having said that, I try to pick songs that I actually like because I realize that I have to live with these songs for a long time, from when I'm working on them in the studio to possibly playing them onstage for the rest of my life. So I try not to pick songs that I know would drive me crazy.
Like, I have had moments, which I think most people have, where you'll be watching TV, and it'll be interrupted by some tragic event, and you'll actually find yourself thinking, 'I don't want to hear about this train being derailed! What happened to 'The Flintstones'?'
It becomes more important to me as time goes on to make every album the best thing I've ever done, so it's a lot of self-imposed pressure that also kind of slows me down a bit.
There's a lot of different ways that a song would be a challenge to parody. There are a lot of songs that would ostensibly be a good candidate for parody, yet I can't think of a clever enough idea. Some songs are too repetitive for me to be able to fashion a humorous set of lyrics around. Some songs flat-out just don't work creatively for me.
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 can't say enough good things about my band. I feel very fortunate that I found them when I did, very early in my career. Not only are they just great, nice guys; they're some of the best musicians you're likely to find. They do everything from gangsta rap to polka music and every genre in between. It's amazing.
