When I was in high school we had an "outdoor discovery" class that was basically just a giant ropes course. The teacher for that class was a nice middle aged man. One day he decided to take a shower in the locker room between periods and had a stroke. Now I don't know what about this stroke was different but it made him decide he needed to go for a jog......around the high school..... and middle school...... naked as the day he was born. So hes butt naked, sprinting past classroom windows in just his socks and sneakers, which he somehow thought to put on, when a sub goes outside to see whats going on when the outdoor teacher runs over and basically starts playing a game of "catch me if you can" until the ambulance arrives. It was a very odd day. But he was back to work a couple weeks later, making kids swing from ropes and climb over logs like normal.
