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 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.
In the '80s, I was the only game in town, I was the only one getting that kind of exposure in any rotation on MTV. Now with internet culture it seems like everyone is doing music parodies. And they're not all good!
I write and write and write, and then I edit it down to the parts that I think are amusing, or that help the storyline, or I'll write a notebook full of ideas of anecdotes or story points, and then I'll try and arrange them in a way that they would tell a semi-cohesive story.
