‘Jackass’ Joins ‘Shark Week’ Sneak Peek, Possible Shark Attack???

“Jackass” is jumping the shark — like, for real — by joining Discovery Channel’s “Shark Week” spectacle, and based on this first look … we’d say someone’s bitten off more than they can chew.

Johnny Knoxville, Steve-O, Chris Pontius and a couple new jackasses are returning to TV later this month for the “Jackass Shark Week Special,” and as you can see … they are up to their same old antics.

Steve-O’s said the guys “went all out” for the special, adding “there were consequences” for doing so, and based on our sneak peek, those consequences were pretty severe.

Check it out … a new ‘Jackass’ member named “Poopies” appears to get attacked by a shark after a jump attempt. Someone’s heard yelling for medical assistance and a tourniquet as the teaser ends.

Yikes.
