‘Jackass’ star Bam Margera has proven that once again, the show and movies were aptly named. This time around, his stunt landed him on an operating table.

Along with pro kayaker Steve Fisher (who really should’ve known better), Margera sailed down a 100-foot Oregon waterfall last week. Fisher stayed in the kayak as planned, but the impact at the bottom launched Bam into the water — and gave him a nasty hernia that required surgery.

He gave a big thumbs-up from his hospital bed, but he’s not ready to rumble just yet. In fact, he may need more surgery later this year.
