Not any specific one, but I was a huge fan of Frank Jacobs, I guess he wrote the plurality of the song parodies for MAD, Sam Hart, a few others, but that was also where I was first exposed to the art form of song parodies.
When I was a kid, I thought I was going to be an architect, because when I was 12 years old I had a guidance counselor that convinced me that that was the best career choice for me.
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.
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.
