“Johnny Knoxville revealed that a stunt involving a bull in Jackass Forever went so wrong that he suffered brain damage because of it.

“As reported by NME, Knoxville was a guest on The Howard Stern Show and talked about how a bull knocked him into the air and left him with not only a broken wrist and broken ribs, but also a concussion that resulted in a brain hemorrhage.

““Yeah, I got a brain hemorrhage from that,” Knoxville said. “So my cognitive abilities were in steep decline after that hit. No one in my family is happy with the stunts. The bull hit was the worst hit I’ve ever taken from a bull, or maybe period. I remember taking some tests.
