10. Derrick Lewis At UFC 229 - 'My Balls Was Hot'
Loveable Heavyweight Derrick Lewis very quickly became the talk of the town as soon as Joe Rogan stepped into the Octagon after his winning performance at UFC 229.
Lewis had just overcome Alexander Volkov by brutally pummelling his rival into the mat in the closing stages of the third and final round. However, in the wake of his win he decided to do something a little unexpected.
'The Black Beast' proceeded to strip off his shorts as soon as the fight was over. Rogan was quick to question why the victor had chosen to do this in the middle of the cage and not backstage.
Without missing a beat, Lewis openly admitted that he took his pants off because his 'balls was hot'. Any other personality would have probably burst out laughing there and then, but Rogan (ever the professional) remarkably kept his composure and simply replied with, 'I understand'. This actually made the entire exchange even more oddly hilarious.
Lewis has proven time and time again that he can be one of the most unpredictable strikers in the Heavyweight division, but on this occasion his unpredictability extended to this now-legendary post-fight interview with Rogan.
