I know for a fact, obviously, because my kids grew up watching the show, that there are some things they are introduced to from 'The Simpsons', and then later in life they see the thing we're parodying. My kids had not seen 'Casablanca,' and we'd done parodies of 'Casablanca.'
We did 'The Simpsons Movie,' which took almost four years; it was the same people that do the TV show, and it just killed us. So that's why there hasn't been a second movie. But I imagine if the show ever does go off the air, they'll start doing movies.
I like all of the early relationship strips that were collected in 'Love Is Hell,' where I pretended to be an expert in relationships and did comics like 'The Nine Types of Boyfriends,' 'Sixteen Ways to End a Relationship,' 'Twenty-Four Things Not to Say in Bed,' and other arbitrarily numbered lists.
Charles Schultz is a really interesting case. He wrote that comic strip and drew it himself from beginning to end, and it's a work of genius. It's very simply drawn, but it has some really deep emotions that you don't expect in a silly-looking comic strip.
I went through a phase where people would introduce me at parties as a cartoonist, and everybody felt sorry for me. 'Oh, Matt's a cartoonist.' Then people further feeling sorry for me would ask me to draw Garfield. Because I'm a cartoonist, draw Snoopy or Garfield or something.
