MSNBC; Smialowski/GettyKeith Olbermann hit back at Newt Gingrich's claim he hosted a biased political debate.

Newt Gingrich and Keith Olbermann are at it again.

The two haven't gotten along since Olbermann slammed Gingrich for his remarks on the First Amendment in 2006, and have continued to spar over issues including welfare and other policies.

Now four years later, the former House Speaker told C-Span this morning that if Presidential debate organizers wanted him to participate in their forums, they would have to agree to some of his demands – most importantly, no Keith Olbermann or Chris Matthews as the moderators.

NBC, which employs both Olbermann and Matthews, is co-hosting the first Republican presidential debate in the spring of 2011 with Politico.

"I would not participate if it was a hostile reporter asking 'gotcha' questions with a certain time limit," he said on C-Span’s Washington Journal. "There's no possibility that I would ever go to a debate and have (MSNBC's Keith) Olbermann or (MSNBC's) Chris Matthews asking questions."

But Gingrich prompted a re-upping of the historical feud when he mistakenly said he thought Olbermann and Matthews had co-hosted a debate a few years ago.

"I watched the debate a couple of years ago and it was an embarrassment because they were so relentlessly hostile and they were so left-wing that every question they asked of the Republicans was designed to embarrass and divide the Republicans," Gingrich said on the show. "And every question they asked the Democrats was designed to make them look good. Well, why would we participate in that?"

Upon hearing the comments, Olbermann immediately took to Twitter to ridicule Gingrich.

"Just read Gingrich ripping me for my questions last time I moderated a GOP debate," the MSNBC host tweeted. "But I've NEVER moderated a GOP debate!"

He punctuated his post by adding the Twitter hashtag #delusional, a winking gesture to make fun of his opponent. "On C-Span, Newt appears to think Chris Matthews and I co-moderated a GOP debate AND a Democratic debate. We did neither," he later tweeted, also adding the Twitter hashtag #NewtsNuts.

His supporters flooded Twitter to help mock Gingrich’s comments, adding their own tongue-in-cheek insults which Olbermann re-posted.

"You were terrible that time you hosted the Oscars too!" one supporter tweeted.

"Yeah, Olbermann, you messed up the Lincoln-Douglas debate too," another wrote.

Olbermann supporters continued to pile on the exaggerated insults, joking that he did a terrible job as the Vikings quarterback today, failed as the 2008 GOP presidential nominee, was the cause of rain at Woodstock, broke up the Beatles, and more.

Olbermann, clearly having gotten his point across, did take responsibility for one thing.

"On the other hand," he admitted, "that WAS me in those Boston Market commercials."

As of Sunday night, Gingrich had not responded – at least not coherently. At approximately 6:30 he tweeted, "Uyyy."
