Superstar stuntman Steve-O made famous by his shenanigans on Jack Ass challenged St Ives to a raft race yesterday... and crowds turned up to take on the troublemaker.

Posting on Twitter, Steve-O said: "Yesterday in Cornwall I challenged my Snapchat followers to build homemade rafts and meet up for a raft race at the beach. "Twelve rafts and hundreds of people showed up-- and I won the first of two serious races on the raft I built. Thanks so much to everybody who worked so hard (and those who traveled so far) to make that such a good time.

Steve-O was in Cornwall with his girlfriend Stacy Soloman, with the couple also enjoying a spot of surfing at Sennen.
