Somebody will come up to me after a show and have me sign their arm, and the next time I see them my autograph has been permanently inscribed on their arm.
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.
I was a huge fan of 'Mad' magazine when I was 11, 12, 13 years old. I'd scour used bookstores trying to find back issues, and I'd wait at the newsstand for a new issue to come out. My life revolved around it.
I like to think that I've gotten better at what I do. I spend more time and pay more attention to detail album after album. But pretty much it's stayed the same.
I tend to enunciate pretty well. It's always seemed that my voice is one of those voices that people can recognize pretty easily - which has been a bit of a drawback for some characters because you're supposed to lose yourself in the character, but sometimes people look at a character and go "Oh, it's 'Weird Al.'"
I cut my teeth playing rock songs on the accordion when I was a teenager and my friends always thought that was extremely amusing. I think that was the genesis of my polka medleys, because every rock song I played on the accordion just sounded like a polka and my friends thought it was funny. So that was a joke that I continue up to this very day.
It's hard to really articulate what the parameters are that make one song parody-able and another song not, but if I can come up with a good enough idea for it, I go for it, and if not, then I have to move on.
