The Simpsons mocks Karl Rove in their latest episode. (YoutTube)

The opening credits for Fox's "The Simpsons" on Sunday took aim at political commentator Karl Rove for his comments on election night.

The message Bart Simpson wrote on the chalkboard was, "I will not concede the election till Karl Rove gives me permission."

This was a reference to Rove's refusal to accept the call from Fox News' decision desk that President Obama had beaten Mitt Romney a little after 11 p.m. last Tuesday night.

Rove insisted it was an "early call," wanting to wait for all votes from Ohio to come in. His denial led to a disagreement between him and Fox host Megyn Kelly

"They are not listening to Karl," Kelly eventually said of fans celebrating Obama's win in Chicago. "They don't care what Karl said."

The Simpsons got political late in the game this year, with Mr. Burns' dubious endorsement of Romney, a poll worker poking fun at voter ID laws, and a scene in a voting booth where Homer Simpson votes Republican based on his assertion that Romney "did invent Obamacare."

"Thank you for voting for Mitt Romney," the electronic voting machine says to Homer after he touches the red Romney option on its screen. "You may now see his tax returns."
