Conor McGregor -- I'll Crush Jose Aldo But ... I'm Not F**king With Liam Neeson (VIDEO)

UFC superstar Conor McGregor dropped a ton of knowledge on us -- about his upcoming fight, his super ballin' watch, and even crowned Ireland's true king of badassery.

Where to start? First off ... you've gotta see the timepiece the reigning featherweight champ is rocking in this clip -- Conor says it's the ONLY one in North America ... which explains the $200k price tag!

Then Conor talked some smack about rival Jose Aldo and their Dec. 12 fight. His words of inspiration? "Show the f**k up!" There's more, but that's the Cliff's Notes.

And best of all -- 'The Notorious' one weighed in on who's top dog in Ireland right now ... with himself, Liam Neeson, and Bono (yes, the little guy from U2) on the ballot.
