A certain private school was recently faced with a unique problem.  A number of 12yr old girls were beginning to use lipstick & putting it on in the bathroom.  That was fine, but after putting on the lipstick they would press their lips to the mirror leaving dozens of little lip prints.

Every night the maintenance man would remove them, & the following day the girls would put them back.  Finally the principal decided something had to be done.

She called all the girls to the bathroom & met them there with the maintenance man.  She explained all the lip prints were causing a lot of extra work for the cusodian who had to clean the mirrors every night.  And to demonstrate this she asked him to show the girls exactly how much effort was required.

The custodian took out a long-handled squegee, dipped it in the toilet, & proceeded to clean the mirror with it.  Since then, no more lip prints.
