THIS is the hilarious moment a man took an unexpected trip into the freezing waters of Victoria Harbour in Greenock

The clip, which has gone viral on Facebook, shows the man casually strip topless as he walks along the street with friends before sprinting towards the water.

But as he prepares to divebomb into the Clyde, he trips and tumbles head first down the 15 foot drop.

One person commented on the clip on Facebook saying: "He's taken quite a chance - if there was a boat there it would have been a nasty landing!"
