This is the moment two boys tried to show off by pulling a motorcycle wheelie at a junction - only to fell straight off.<br /><br />The youngsters were waiting at a junction in Ayuttaya, central Thailand, when the rider tried to perform the stunt on December 11.<br /><br />But they were left red-faced in front of the other motorists when the wheelie failed and they both hit the ground.<br /><br />Driver Apichat Teerabudwongkool said the two teenagers ''though they were being cool'' by trying to do a wheel.<br /><br />He said: "The two boys love to show off. First, they were burning tires and revving the engine. But when they tried to do a wheelie they fell down.<br /><br />''They had a small accident and it serves them right. Hopefully, it will be a lesson for them and they will be more careful in the future.''
