• Sean McInerney was bitten by a shark while wakeboarding in shark-infested waters
  • The "Jackass" star was attempting to perform a stunt for Discovery's "Shark Week" special
  • McInerney suffered a deep bite to his left hand and sustained artery and tendon damage

A water stunt for Discovery's annual "Shark Week" special ended with daredevil Sean McInerney getting bitten by a shark.

The "Jackass" star — nicknamed Poopies — was attempting to wakeboard across shark-infested waters over a ramp in an attempt to literally "jump the shark," Entertainment Weekly reported.

The move was inspired by a 1977 episode of the sitcom "Happy Days," in which the character Fonzie (Henry Winkler) jumps over a shark while on water-ski, the outlet noted. The phrase "jumping the shark" has come to refer to the idea of resorting to wild gimmicks to promote something that was once, but no longer, popular, according to The Independent.

McInerney, however, fell from his board while performing the stunt and was bitten by a shark on his arm and hand after entering the water.

The incident left McInerney with an injury on his left hand from one of the animals' bites.

Footage of the incident shared by Discovery Tuesday — which marked the start of "Shark Week" this year — showed crews rushing in to pull McInerney out of the water and perform medical aid on him.

McInerney received a deep bite to his hand and sustained artery and tendon damage as a result, reported.

"Poopies is doing great, they were able to repair all the damage," McInerney's "Jackass" co-star Chris Pontius said in the Discovery video. "If you're in the daredevil business, you know, you expect and you accept that some things are gonna go wrong every once in a while."

McInerney said he never thought he would get bitten by a shark despite knowing there was a chance it would happen.

"I definitely got a degree in shark college there," he said in the video. "I don't blame the sharks at all. I mean, I was in their living room, and it was dinnertime."

Fellow "Jackass" member Stephen Glover, also known as Steve-O, posted a photo of McInerney's injuries to Instagram Monday, showing the latter's hand being covered in stitches.

"[McInerney's] hand gets completely mangled on our Jackass #SharkWeek special," Glover's caption read. "Go ahead and follow [McInerney] now because, trust me, he's about to blow the f--k up."
