Retiring after 20 years, a United States Marine Corps gunnery sergeant 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 his upper torso. Fortunately the cast fit under his shirt & sport coat quite well and wasn’t noticeable.
On the first day of class, he found himself assigned to the toughest students in the entire school. The smart-aleck punks, having already heard that the new teacher was a retired Marine, were leery of him and he knew they would undoubtedly be testing his toughness and level of discipline immediately.
Walking confidently into the rowdy classroom, the new teacher opened a couple of windows 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.
And the rest of the school year went very smoothly.
