This school was having problems with lipstick. Young girls would put it on and press their lips to the mirrors in the bathroom to blot it. They left lip prints everyday.

The janitor would have to clean the mirrors every night. Finally the principal decided to fix the problem. She brought the girls in and had the janitor show them how he cleaned the mirrors.

He took his squeegee and dipped it in the toilet and then used it to clean the mirrors. There were no more mirror blots after that.
