Jacob Volkmann gained notoriety in 2011 when he was visited by the Secret Service after claiming he wanted to beat up Barack Obama, and he doubled-down on his criticism of the President later that same year.
“Obama needs a glassectomy. Ask me what a glassectomy is, Joe,” Volkmann instructed Rogan in the Octagon, to which he reluctantly obliged.
“It’s where they remove the belly button and put a piece of glass in there so you can see what you’re doing while your head’s up your ass.”
The joke went down like a lead balloon with both Rogan and the crowd, who began booing him.
”He kind of ruined it for me,” Volkmann complained backstage to reporter Ariel Helwani. “Yeah, he did. He ruined it. I wanted to punch him in the nuts!”
Rogan didn’t rise to the bait, but coincidentally, a couple of years later, technical advice he was loudly articulating during a broadcast appeared to help Bobby Green defeat Volkmann.
