The Jackass boys are up to their old tricks, with one exception: this time there's a plot–sort of. Although the narrative effectively piggybacks an array of stunts, it's little more than a shock-comedy showcase. Johnny Knoxville stars in the titular role as 86-year-old Irving Zisman who lugs his eight-year-old grandson on a cross-country road trip. Though there are nearly eight decades between the octogenarian and the grandson they share much in common–like a sense of humour and maturity level. Although this movie is not for the faint of funny there are some endearingly-sappy moments that balance the barrage of (sometimes literal) funny shit. If Johnny Knoxville et al usually make you laugh out loud then you'll love Jackass Presents: Bad Grandpa–if you're not typically a fan, well, consider this a warning.
