Jim's Overalls

Jim was a gardener.He had no work to do for a few months.
One day while walking along the street,he saw a sign for taking on a man who could grow flowers and trees well.
Jim was so pleased that he went directly to answer the sign.There the master told Jim to bring his overalls with him.Jim did what he was asked.The master examined his overalls and then decided to let Jim have the job.
Curiously Jim asked him why his overalls were so important.The master said, 'Oh,your overalls are all with patches on kneels.I have dismissed two men whose overalls were with patches on the buttocks.'
