Ultimate Fighting Championship (UFC) featherweight contender Conor McGregor was a guest on SI Now earlier today (Fri., Nov. 21, 2014) and the "Notorious" featherweight was asked if he could defeat WWE superstar "Sheamus" in a real fight.

His answer? "I would whoop his ass. It would be no contest."

Then this happened.

Had bigger dumps after a salad @TheNotoriousMMA lad. U can hold @BrockLesnar's @WWE title while the big boys duke-it-out. Win @ufc title 1st — Sheamus (@WWESheamus) November 21, 2014

@WWESheamus @BrockLesnar @WWE 'Never connected' sounds more like your game. You wear ball stranglers and slap mens asses for a living. — Conor McGregor (@TheNotoriousMMA) November 21, 2014

Whereas you talk for a living son & we all know who's ass @TheNotoriousMMA is kissing nightly. #LittleManBigChip — Sheamus (@WWESheamus) November 21, 2014

@WWESheamus I'll whoop you at your own game, then we can toast a whiskey and talk about true fighting. Always remember #UFCAsRealAsItGets — Conor McGregor (@TheNotoriousMMA) November 21, 2014

Whiskey in Dublin this Christmas @TheNotoriousMMA. Shirts on the deck, back-to-back, and we'll fight everyone. #TraditionalIrishChristmas — Sheamus (@WWESheamus) November 21, 2014

Sheamus stands 6'4" and weighs roughly 270 pounds.

Predictions?
