Are you saying that Jack Burns got fired from writing for The Muppet Show because of attitude problems? I never knew that. Of course, Jack Burns did get hired to write The Muppet Movie.
In Bernie Brillstein's incredible biography, he writes about his working relationships with his clients. In the case of Jim Henson, he spoke of how non-confrontational he was. There was some kind of problem with Jack Burns-like he thought he knew the characters better or could write better for them-whatever. During a phone conversation with Brillstein, Jim, in his own gentle way simple said "Jack Burns gives me a stomach ache.". Bernie knew exactly what he meant, said he would take care of it, a call was made and he was gone.
I would assume Jack's work on Muppet Movie was done before all this. I never saw him on the set, or doing any promotion for the film. I met David O'Dell who came in came in kind of late, so perhaps he filled in for Jack(?).
The only major contributions to the Muppets I know of is Burns named Fozzie's writer "Gags Beasly" (and "Gags" he'd used before), named Gonzo and helped establish his personality.
