It's from DyHrdMET:
Can you tell the story of how you got to THE SIMPSONS and came up with this story idea?
My partner, David Isaacs and I were friends with the late Sam Simon and had worked with him on a couple of other shows. When he became the showrunner for THE SIMPSONS he asked if we would write one. At the time they paid much less than a standard live-half hour sitcom. Because they were animated, the studio was able to get away with paying essentially the same as a Saturday morning cartoon. But we were fans of the show, wanted to help Sam out, and my kids were little at the time and Sam promised them jackets and toys. That’s really why we did it – for the swag.
There are a lot of inside jokes and references to the International League in that episode – shamelessly so. Also, if you watch the episode, freeze frame the outfield signage for more jokes.
As I recall, the three of us (me, David, and Sam) worked out the story in a morning. I’m here to tell you, the real creative force behind THE SIMPSONS was Sam Simon. The tone, the storytelling, the level of humor – that was all developed on Sam’s watch.
Other quick notes about that episode:
I got to be the voice of the Springfield Isotopes. The name I used was Dan Hoard, who was my broadcast partner in Syracuse and now is the radio voice of the Cincinnati Bengals and the U. of Cincinnati Bearcats.
Tony Bennett got to sing the Capitol City song.
And we're on the bonus track of the DVD.
Writing the script was a blast. I remember saying to David that there was so much you could do with these characters that I thought THE SIMPSONS could go five or even six seasons. They’re on what, year 35?
