According to a news report, a certain school in Garden City, MI, 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 restroom. That was fine, but after they put on their lipstick, they would press their lips
to the mirror leaving dozens of little lip prints.
Every night, the custodians would remove them and the next day, the girls would put them back.
Finally the principal decided that something had to be done. He called all the girls to the restroom and met them there with the custodian. He explained that all these lip prints were causing a major problem for the custodian who had to clean the mirrors every night.
To demonstrate how difficult it had been to clean the mirrors, he asked the maintenance man to show the girls how much effort was required. The maintenance man 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.
