Mike Ditka: TOTAL FART DENIAL ... 'It Wasn't Me'

Mike Ditka says he's a denier ... not a supplier ... when it comes to an alleged fart on the set of "Monday Night Countdown" -- insisting he didn't rip ass on Cris Carter.

It certainly sounded like he did ... and Cris Carter's reaction sure made it seem like he did ... but Ditka told the Chicago Sun-Times point blank, "It wasn't me."

He expanded on the matter ... "Believe me, I’m to the point in my life where it doesn’t matter. One day I’ll be happy if I can leave a fart."

"Right now, it wasn’t me. I don’t care what they think. They can think anything they want."
