According to DRG, Brock blades the back of his head
Yeah, in my defense I was just making claims to troll since I wasn't watching the show. I caught that part and replayed it. If Brock bladed, he is more talented at doing so than Trip and Flair combined. It looked like when he went in; his head went on the inside of the post and caught the bolt that holds the turn buckle. He was bleeding before he hit the ground, so I would say that this wasn't a blade job as well as going as far as saying HHH's butt was wet thanks to the water that ran down his shirt mixed with wicked swamp ass, not the pissing out of the butthole so many claimed.
Also, "Weed the people" and it's gloriousness of all things not funny has reached the mass media market, sealing the deal for me as having little to no comedic value left.
