While Khalil Rountree is known in the UFC for being one of the most aggressive and violent fighters, outside the octagon he doesn't like jokes, much less tolerate disrespect. And the influencer 'The Greatest Entertainer' discovered this the hard way, deciding to play a prank on the former UFC light heavyweight (up to 93 kg) title challenger at Mr. Olympia 2026, the world's premier bodybuilding championship, held in Las Vegas last weekend.

In his pranks, 'The Greatest Entertainer' often 'plays' with muscular, large men, giving them a 'chest bump'/bump. When he did the prank with Rountree, the influencer immediately regretted it.
With a grim expression, Khalil grabbed 'The Greatest Entertainer' by the arm, who ignored him. Immediately, the UFC fighter took down the influencer who, upon getting up, pushed him. Without hesitation, 'The War Horse' advanced and pushed the man even harder. It's unclear at this point whether it was staged. In any case, it's best not to mess with Rountree under any circumstances.
Watch out for the prank!
