This is the hilarious moment a show-off teen tries to do a 'parkour' front flip off a bench - but ends up flat on his face as the bench COLLAPSES underneath him.

Jordan Mackay, who was just 15 when the video was filmed, can be seen leaping onto the park bench with a determined look on his face, as he stretches up his arms to launch into a flip.

But instead, the teen got an unexpected shock - when the square bench gave way beneath him, sending him sprawling onto the grass.
