Steve-O has opened up about the one stunt that was too much even for the foolhardy cast of Jackass.

The franchise has returned again for what will be the final outing for the gang, Jackass: Best and Last, with the cast once again setting out to undertake the dangerous and disgusting for the their fans.

Needless to say, the crew have already carried out plenty of inadvisable stunts at home, repeatedly putting the ‘don’t’ in ‘don’t try this at home’.

These have involved alligators, teeth being tied to cars, and an unnerving quantity of faeces over the years.

But while no-one can accuse the Jackass cast of not being willing to put themselves in physical danger for the entertainment of their fans, one stunt took things just too far, even for them.

With the new movie out, footage of the stunt has resurfaced on social media.

Steve-O revealed that the plan had involved a ski slope, and a bouncy castle.

“When we were shooting Jackass 3D we went up to Northern California to film a bunch of snow stunts,” he said.

“They had a big bounce house on a ski slope headed for this Olympic ski jump, and the idea was to have the whole cast in it,” Steve-O explained.

So all the cast would pile into the bouncy castle, and then be thrown around inside it like ice cubes in a cocktail shaker as it barrelled down the slope.

“Even though we hated the idea of our heads clashing together in the bounce house, we probably still would have done it,” said Steve-O.

But while tumbling down a slope together like sardines in a can is all well and good, sort of, there was one really quite big problem. A 500 pound problem to be precise.

“There was a huge generator which kept the bounce house inflated which would have to follow behind it,” explained Steve-O, “and the thing was 500 pounds.”

He added: “We just were not willing to have that generator land on us and crush us to death, so the whole cast backed out, maybe the first time the whole cast backed out of a stunt ever.”

It turns out even the cast of Jackass weren’t too keen on 500lbs of metal following them down a ski slope, bouncy castle or no bouncy castle.

Steve-O was not the only cast member to open up about some of the worst stunts, with Wee Man telling the Origin Stories podcast about one type of stunt he wouldn’t do.

“Not that I’ve been involved in, but anytime they did poop, poop is the worst. Poop is the worst,” he said. “It stinks. It’s horrible. Nobody wants to be around poop, you know?”

The wildest stunts from Jackass

Paper Cuts – Jackass: The Movie

While on paper (get the pun?) it’s perhaps the most basic stunt, this one should be in the Jackass Hall of Fame for being the most painful.

Ryan Dunn gave Johnny Knoxville and Steve-O paper cuts via an envelope in the most sensitive places, such as between the toes, between the fingers, the corner of the mouth, and worst of all, on the tip of Steve-O’s tongue.

Despite these guys regularly seeing all sorts of disgusting bodily fluids, this stunt sent the camera crew into a frenzy of puking.

Butt X-Ray – Jackass: The Movie

In the 2002 movie, Ryan Dunn placed a toy car, which was in a lubed-up condom, into his own rectum.

He then went to a proctologist under the guise of a frat party accident, and after Dunn’s nether regions got a quick scan, the reactions of the medical staff were secretly recorded for the amusement of the Jackass audience.

Having a toy car up your arse is apparently so embarrassing that the doctor told Dunn to go straight to the hospital and not tell anyone about it.

Lamborghini Tooth Pull – Jackass 3D

Now, this one is bad.

As the title of the stunt suggests, for the 2010 movie Ehren McGhehey allowed his ‘crooked’ tooth to be yanked out on a piece of string that was attached to a Lamborghini, which of course set off at significant speed.

Speaking to GQ a decade after the horrifying stunt, McGhehey said that the stunt ‘broke my face all the way up to my eyeball’.

“It took nine months to heal.”

Poo Cocktail Supreme – Jackass 3D

Possibly one of the most disgusting Jackass stunts to ever exist, the Poo Cocktail Supreme saw Steve-O get strapped into a portaloo that was attached to a bungee system, and then get flung around as the contents of the toilet engulfed him.

Yep, he was literally covered head-to-toe in sh*t, resulting in the crew physically vomiting when he stepped out.

Steve-O later revealed to journalist Graham Bensinger that due to health and safety, they used dog poo instead of human… as if that makes things any better?!

The Toro Totter – Jackass Number Two

In the 2006 movie, Knoxville joined his Jackass co-stars Chris Pontius, Ryan Dunn and Bam Margera on a teeter-totter, which was in an enclosure with an angry bull.

Despite animal rights group PETA slamming the production for repeatedly using animals as a form of entertainment, this is undoubtedly one of the most outrageous stunts the Jackass guys were involved in.

Knoxville was the only one left after the bull managed to charge the others away, with him getting absolutely thrashed against the frame of the teeter-totter before making a lucky escape.
