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 in 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 who had to clean
the mirrors every day. To demonstrate how difficult it was to clean the
mirrors, she asked the custodian to clean one of the mirrors. He proceeded to
take out a 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.
