10. The Brooklyn Bus Attack
This could be higher but some fans think this was epic. In short, McGregor wanted revenge on Khabib for intimidating Artem Lobov. So his natural response was to fly a group of 20 goons over to Brooklyn from Ireland by private jet. They then proceeded to rampage through the Barclays Center where UFC 223 was going down.

McGregor infamously threw a dolly at the window of a bus carrying several fighters including Khabib. Two fighters got glass in their eyes, preventing them from fighting in the event. Meanwhile, NYPD picked McGregor up and he spent the night in a precinct. This was absolute chaos but still used to promote McGregor’s pending bout with Nurmagomedov.
