Lipstick

According to a recent news report, a certain private school in Manchester was recently faced with a unique problem. A number of 12-year-old girls were beginning to use lipstick and would put it on in the bathroom. That was fine, but after they put on their lipstick, they would press their lips on the mirror, leaving dozens of little lip prints.
Every night the caretaker would remove them, and the next day the girls would put them back. Finally, the headmaster decided something had to be done. He called all the girls to the bathroom and met them there with the caretaker. He explained that all these lip prints were causing a major problem for the caretaker, who had to clean the mirrors every night.
To demonstrate how difficult it had been to clean the mirror, he asked the caretaker to show the girls how much effort was required. He took out a long-handled squeegee dipped it in the toilet, and cleaned the mirror with it. Since then, there have been no lip prints on the mirror.
