DVD: Jackass 3D (18)

One's enjoyment of the Jackass franchise probably depends on one's ability to laugh at seeing a 35-year-old man get punched in the groin.

The groin punch being the recurring motif in Johnny Knoxville, Steve-O, Wee Man et al's world of brotherly pain. Their stunts may lack nuance – one here sees the group's tubby member have an apple retrieved from his backside by a sow – but their juvenile genius still succeeds at constructing silly scenarios that make one's inner 13-year-old male guffaw pathetically. It's dumb, painful fun – and it's hard to contain one's admiration for a film so gross that even its cameramen frequently vomit in shot.
