A principal of a small middle school had a problem
with a few of the older girls starting to use lipstick.
After applying lipstick in the bathroom they
would then press their lips to the mirror and
leave lip prints
[purportedly practicing the perfect pucker].

Before it got out of hand he thought
of a way to stop it. He gathered all the girls together
who wore lipstick and told them he wanted to meet
with them in the ladies room at 2 pm.

They gathered at 2pm and found the principal
and the school custodian waiting for them.

The principal explained that it was becoming
a problem for the custodian to clean the mirror
every night. He said he felt the ladies did not
fully understand just how much of a problem
it was to remove the waxy lipstick, and
he wanted them to witness just how hard
it was to clean. The custodian then demonstrated...

He took a long brush on a handle out of a box.
He then dipped the brush in the nearest toilet,
moved to the mirror and proceeded to remove the lipstick.

That was the last day the girls
pressed their lips on the mirror.
