Talk about sore losers. 

MSNBC Boss Phil Griffin was happy when MSNBC's Rachel Maddow beat Fox News Anchor Megyn Kelly in the Monday night debut in prime time. Kelly won in total viewers, but lost to Maddow in the demos.

The next night, Kelly killed Maddow in the demos.  

"I have never seen it in all my years of cable," says Phil Griffin.

Griffin, president of MSNBC, says there's something fishy about Tuesday's ratings for the Fox News Channel, which were up significantly from a day earlier when Fox News debuted its new schedule. And he wants an investigation.

It is impossible." Griffin continued, "I have never seen it. They did election-night numbers in the demo Tuesday."

According to The Hollywood Reporter the Nielsen numbers Griffin refers to include MSNBC beating Fox News on Monday in the adults 25-54 demographic at 7 p.m. and tying Fox News at 10 p.m.

At 9 p.m. on Monday, MSNBC's The Rachel Maddow Show beat Fox News' new The Kelly File, hosted by Megyn Kelly, by a slim 10,000 viewers in the key demo.

By Tuesday, though, Fox News was back to its dominant self, with 573,000 in the key demo compared with 261,000 for MSNBC between the hours of 8 p.m. and 11 p.m.

Perhaps most dramatically, Kelly's narrow loss to Rachel Maddow from a night earlier was significantly reversed, with Kelly drawing an audience of 623,000 in the key demo compared with Maddow's 291,000.

Nielsen has not yet responded to Griffin's remarks.

On Wednesday, Kelly beat Maddow 384,000 to 299,000 in the key demo, with CNN's Piers Morgan Live at 117,000. And on Thursday, Kelly beat Maddow 376,000 to 288,000, with Morgan at 157,000.

Griffin's assertion that Fox News did "election night" numbers on Tuesday may have been hyperbole, considering on Tuesday Fox News had 2.65 million in primetime and 573,000 in the key demo, while on the night of the presidential election Fox News had 7.5 million viewers with 3 million from the key demo, according the Nielsen.
