Jackass prankster keeps an eye out

SLAPSTICK superstar Johnny Knoxville was relaxing in his hotel after his latest on-set mishap when some dried blood in his nostril caused him to blow hard and his eyeball popped out.

Luckily, he hadn’t been eating hot and sour soup or taking a bubble bath, and he was able to reach under, scoop it up and push it back into its socket.

It was the latest in a litany of injuries that would make the blood drain from the toughest stunt professional’s face — but it was far from the most stomach-churning.

“I have, like, 15 doctors for different parts of my body and they all have a special talk with me. I don’t know what to tell ‘em,” Knoxville said.

The star, who rose to fame mesmerizing fans with his shocking stunts in MTV’s 2000-02 reality prank series “Jackass,” was at Las Vegas CinemaCon to promote his new movie “Action Point.”

He recalls a day’s shooting for the movie when he landed flat on his face after flying 6 meters through the air off a slide. Knoxville was rushed to the emergency room with a bad case of concussion and a fractured eye socket.

“I go back to the hotel room and I blow my nose because I had blood there. My left eyeball just pops out of my head. It’s like a cartoon. I was like, ‘Oh no!’ I pushed it back in and I called the producer,” he said. “I was like, ‘You’ve got to come get me. My left eyeball just popped out of my head.’ He’s like, ‘Ah ha ha ha ha!’ I’m like ‘I’m serious.’ He goes, ‘I’ll be right there.’”

In “Action Point,” due out on June 1 in the US, Knoxville, born Philip John Clapp Jr, plays a daredevil who designs and operates his own theme park with his friends. The comedy is inspired by Action Park, which opened in 1978 in Vernon, New Jersey, and built up a reputation for poorly designed, unsafe rides and intoxicated and underage staff.
