I'm only going to mention this one because I wasn't involved. A chemistry teacher known as "Wild Bill" Brooks once opened the door to his classroom and found all the students lying on the floor and the smell of gas in the air; one of the Bunsen burners was hissing but not lit. He instantly picked up a chair and threw it through the window with a great crash. At that point all the students stood up. The foolish ones laughed at Mr. Brooks, while the more intelligent ones felt like fools...
