[HOLY S**T!] Video - Conor McGregor Punches Old Man in Head!

[OctoberRed]

Conor McGregor uncorked a shot to the head of an elderly man in an Irish bar in a dispute over whiskey -- Conor's whiskey -- and TMZ Sports got this video showing the violence.

The absurd attack went down at The Marble Arch Pub in Dublin on April 6. Conor walked in and lined up cups for bar patrons ... looking to buy a round of his Proper Twelve for everyone. The problems started when the guy opted out. Conor placed a cup in front of him not once, but twice ... and he still refused.

Unclear if words were exchanged between them, but after Conor downed a shot with the other drinkers, he unexpectedly threw his notorious left fist and decked the old man who rejected the shot.

Two people immediately grabbed McGregor and pulled him out of the bar. The violence was reported to cops, who announced back in April they'd opened an investigation. It's unclear if that's still active, but there are no reports Conor was ever charged -- even though cops have reportedly seen this video.

Perhaps most odd of all ... the poor, old pub patron who got socked didn't even get knocked off his stool. People are just tougher in Ireland, apparently.

It's funny how there's hardly any reaction to this from the other patrons.

Why is it odd? Floyd already exposed that McGregor has no power.

[Cadet Bonespurs]

Say what you want about Floyd, Atleast he only hits women and not old men.

[Albanianboxing]

Conor is an absolute train wreck now. He is done being an elite fighter and his marketing for his whiskey is going to tank after this... Guy let drink and coke destroy him. Should have stayed disciplined in the fight game but the money changed him.

Sounds about white

I was a big fan when he first started out.
He's gone from a working class hero to a complete a**hole.
Behave like that in Belfast and he would get kneecapped.
However he isn't part of the community anymore..jets back and forth from Vegas with his wannabe gangsters..total and absolute disgrace!

[FinitoxDinamita]

Im not surprised because I know couple heads who went from rags to riches and they tend to act that way.

He is acting up because he made 100 million overnight. Im sure he feels invincible.
