A vocational school taught gardening to newly released convicts. They were asked to grow flower plants in their homes. After teaching them for three months, the teacher asked them to bring flower pots with plants to evaluate their training.
On the due date of examination, all the students brought very beautiful pots with flowering plants. The teacher was very much pleased and asked all to donate those plants to the school in exchange of very good marks. The students agreed.
The teacher gave all of them more than 80% marks and posted the list of marks to the head office. Next day, he silently called a manager of a private nursey which sell flower plants and sold all flower pots for a good sum.
The next day a stream of people living in the neighbourhood of the school gheraoed the school. One of the man complained to the Principal, " Sir, all your students have stolen flower plants of all the residents of our colony"
