Johnny Knoxville won the box office last weekend, knocking off an Oscar contender starring Sandra Bullock and George Clooney. Before you give yourself an aneurysm thinking about the series of events that led to that being an actual thing that happened, allow the Jackass genius to regale you with the tale of how he developed his penchant for pranking everyone he's ever met.
On Wednesday, Knoxville was on Conan to promote Bad Grandpa when he was asked how he cultivated his skill and the actor revealed that he learned most of what he knows from his pop. He expands on that statement by describing a prank that his father used to pull when Knoxville was a teenager.
HINT: It involves a hot dog and a microwave and a zipper.
