Richard Appel came in at the tail end of the best of The Simpsons and was around for the last few good years.  He then went on to higher places at FOX and became a writer/producer for various other animated programs.  He’s going to continue doing that for at least three more years.  The Hollywood Reporter describes the deal as a “rich seven-figure pact”.  Good for him.  Right now he’s working on Family Guy Spinoff #2.  Uh, less good for him, but whatever.  It’s always nice to see people who worked on the show doing well.
