* MagnumOpusDissonance: The only reason ''WesternAnimation/TheSimpsons'' exists is because when Groening was in James L. Brooks' waiting room he realized he'd have to give up the ownership of ''Life In Hell'' if it were animated. ''The Simpsons'' went on to become a massive hit while ''Life In Hell'' stayed more underground.
* WhatCouldHaveBeen: If ''The Tracy Ullman Show'' hadn't required Groening to give up ownership, ''Life In Hell'' would have become an animated series and the world would never have seen ''The Simpsons''.
