A former Sergeant in the Marine Corps took a new job as a high school teacher.
Just before the school year started, he injured his back. He was required
to wear a plaster cast around the upper part of his body.
Fortunately, the cast fit under his shirt and wasn't noticeable.
On the first day of class, he found himself assigned to the toughest
students in the school.
The smart-aleck punks, having already heard the new teacher was a former
Marine, were leery of him and he knew they would be testing his discipline
in the classroom.
Walking confidently into the rowdy classroom, the new teacher opened the
window wide and sat down at his desk.
When a strong breeze made his tie flap, he picked up a stapler and stapled
the tie to his chest.
The rest of the year went very smoothly.
