THREE-D would seem tailor-made for the guys from Jackass.

When the technology is used for its funniest and most entertaining purposes, as it was in Piranha 3D, it’s all about the wild, gratuitous gimmicks. I don’t need to be immersed in Pandora; I want stuff flung at me from the screen.

Johnny Knoxville and company, who are constantly outdoing themselves with crazy and creative pranks and stunts, would seem to be just the right guys to do that sort of thing. But very little occurs in their latest movie, Jackass 3D, that wouldn’t have sufficed in 2D.

Sure, there’s an amusing and effective bit involving archery with a sex toy rather than an arrow. Steve-O and Dave England play tetherball with a beehive — dressed in nothing but furry bear hats and tighty-whities — and it feels as if the worked-up insects are swarming around us, too. Weiner baseball, which is exactly what it sounds like, is good for a laugh because it’s presented in artful slow motion (and man, is there a lot of penis in this movie).

But more often than not, this third instalment in the franchise, directed as always by Jeff Tremaine, doesn’t take full advantage of its visual potential. A Jet-Ski stunt Knoxville performs in a swimming pool, which is featured prominently in the trailers, is a bit of a let down, for example. He and his buddies good-naturedly injure themselves by jumping into/over/on stuff using skateboards, motorcycles, wheelbarrows, you name it. It’s their bread and butter — you’ve seen it countless times before.

Similarly, a lot of what goes on here is the typical let’s-see-what-happens silliness. Bam Margera has super-sticky glue squirted on his hands, places them on a couple of heavyset guys’ hairy chests (one of whom is his father, a frequent target of the group’s pranks and a good sport) and then does a little makeshift waxing. Knoxville (dressed in a Santa Claus suit) and another guy (dressed as an elf) climb a 40-foot tree in the snow, only to have it chopped down and go tumbling to the ground with it.

Of course, there is the scatological humour such as the pee-cam, which essentially consists of a guy sneaking up on people and urinating on them with the camera at crotch level. The ‘Poo Cocktail Supreme’ as it’s called, features Steve-O in a portable toilet full of faeces, being tossed into the air repeatedly by bungee cords. (You’ll be happy to know there’s a camera inside the toilet, too, so you can see the full, majestic effect.) Maybe it’s funny if you’re a 12-year-old boy.

Jackass 3D — and the group’s entire oeuvre, if you will — is at its best when it’s about these guys playing well-orchestrated tricks on each other and the world at large. The ‘High Five’ gag off the top — a giant hand on garage-door springs that whaps people to the floor as they’re walking around a corner — is funny every time, especially when Margera gets it with big bags of flour attached. Getting reactions out of strangers always works: In the most effective example, Knoxville — wearing old-man makeup that makes him look like Ted Turner — makes out in public with a much younger girl who’s supposed to be his 19-year-old granddaughter.

The jokes they play involving animals are always hard to watch, though, because you feel so bad for these creatures. Some idiot is invading their pen or whatever just for a laugh, but the ram — or dog, or pig, or donkey — always wins in the end with a swift and powerful kick or head-butt.

So maybe Jackass is about something after all. Maybe it’s a cautionary tale, an age-old parable about man vs nature. Or not.
