It was announced that Fox has renewed The Simpsons for another season. That makes 23.
It was also disclosed that the Fox censors have told the producers of The Simpsons that they can no longer show Homer's bare behind.
There was no word on whether the previous 21 years of episodes - and bare behinds - will need to be edited.
(I must admit to some confusion as to how a cartoon character's backside is considered unfit for viewing. After 21 years.)
