A former Sergeant having served his time with the Marine
Corps took a new job as a 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 even 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 decided to see how tough he really was
before trying any pranks.
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 took a stapler and
stapled the tie to his chest.
He had no trouble with discipline that year...
