I remember watching a Stern interview, Billy West Vs John Kricfalusi 1995 [0]. Kricfalusi came across as petty and self-absorbed, essentially calling West a scab for acceding to management by voice acting multiple characters in later seasons. West claimed the show would be insolvent otherwise and he needed the money. Kricfalusi said this act led to defeat of the creative faction by the executive faction.
I don't know how I stumbled upon it years ago, since it only has ~300 views even now. But i still remember how psychologically manipulative Kricfalusi sounded, and my surprised reaction at the end when Stern sided with him.
