A school teacher injured his back and had to
wear a plaster cast around the upper part of his
body. It fit under his shirt and was not noticeable
at all. On the first day of the term, still with the
cast under his shirt, he found himself assigned
to the toughest students in school.

Walking confidently into the rowdy classroom,
he opened the window as wide as possible and
then busied himself with desk work. When a
strong breeze made his tie flap, he took the
desk stapler and stapled the tie to his chest.

He had no trouble with discipline that term.
