Yes, the first thing I did. We finished the Tracey Ullman shorts into '89, and we started The Simpsons in April '89, and the first thing I did was work out the title sequence.

Wes concentrated on doing the model sheets for the characters, and I think he also took a vacation. So I was left to work out the opening title sequence, and I worked that out with Matt Groening and Sam Simon. I designed the whole idea of coming into the city, talking with Matt and Sam of course, and we came up with different jokes for all the characters. That was the first thing I did.

What would be your favourite blackboard gag or your favourite couch gag?

Well, I've done so many couch gags myself, so my favourite couch gag that I had a hand in was the Escher couch gag.

For blackboard gags, I think there was one we did, "I'm not a thirty-five year old woman." About Nancy Cartwright doing Bart's voice. There's been a lot of them, there's hundreds and hundreds of blackboard and couch gags, but those two come to mind.
