5. Conor McGregor
Some exploits are so stupid that they become iconic. That’s exactly what happened in the case of McGregor in 2018. He had a massive rivalry with the UFC lightweight champion Khabib Nurmagamedov. When the Russian and his crew attempted to intimidate McGregor’s teammate Artem Lobov, McGregor decided to react. Khabib was in Brooklyn, New York for UFC 223 so the opportunity was perfect.
The Irishman gathered about 20 of his cronies and flew them by private jet to JFK. From there, they went to Brooklyn’s Barclay Center where they proceeded to storm the arena. Video footage captured McGregor throwing a dolly through the window of a bus containing several fighters including Khabib. Police later arrested the Irishman and he spent the night in a precinct jail cell.
