John was waiting to cross the road when a blind man approached with his guide-dog. The traffic sign turned green and instead of helping its master to cross the road, the dog raised its rear leg and peed on the shoes of the blind man.
Realising this the blind man reached into his pocket and offered the dog a biscuit
John told the blind man in amazement, "If it was my dog I'd have kicked its @rse! The blind man calmly replied, "I'm going to. But I need to find the right end first".
