Three teenages are riding mountain bikes in a forest, one of them is sloppy and behind. He tries to catch up with his mates. The other two stop quite suddenly to see which way to go down the hill and he passes them like a bullet and he falls flat on the ground. One of his friends asks him: 'Do you feel anything?' He answers 'no'. They give him a yoghurt to drink and he says 'I feel O. Bits of strawberry?' They all laugh about the situation and carry on on their way.
