A COCKY dad, who was showing off on his kids' trampoline, turned into a crashing embarrassment.

Glynn Pennell, 39, was at a family barbecue in Sittingbourne, Kent, when he decided to show his kids his expertise on the trampoline.

Sadly, his back-flip ended with him bouncing over the garden fence and smashing his neighbour's greenhouse.
