"This dog is costing 3000 USD" asked a woman the owner while looking around in pet shop. "Yes" he replied. But I must tell you this dog is a special one. You can send him to buy things in the grocery. Just give him money in the bag and he will do the shoping for you. OK, said a woman, if this is true it's worth that money. Next morning she sends a dog to the market. After she had waited for dog to return for three hours, she went to surch for him and spotted him with female dog having sex in the bush. She imediately phoned to pet store to complain. The owner opologised forgetting to tell her, that the dog has to get the exact sum of money for shopping, otherwise he spents the rest on whores.
