Laloo's stamp

Laloo wanted a special postage stamp issued with his picture on it. So, he instructed his people, stressing that it should be of international quality. The stamps were duly released and Laloo was pleased. But within a few days of release of the stamp, he began hearing complaints that the stamp was not sticking properly, and he became furious. He called the people responsible and ordered them to investigate the matter. They checked the matter out at several post offices, and then reported the problem to Laloo. The report said, "There is nothing wrong with the quality of the stamp. The problem is people are spitting on the wrong side."
