According to a radio report, a middle school in Oregon was faced with
a unique problem. A number of 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 to the mirrors,
leaving dozens of little lip prints.
Finally, the principal decided that something had to be done. She called all the girls to the bathroom and met them there with the custodian. She explained that all these lip prints were causing a major problem for the custodian who had to clean the mirrors every day.
To demonstrate how difficult it was to clean the lipstick off of the mirrors, she asked the custodian to demonstrate. He proceeded to take out a long-handled brush, dip it into the nearest toilet and scrub the mirror.
Since then there have been no lip prints on the mirror...
