Tough Teacher

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 school, 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 year.
