There's a sad proverb saying that those who know how to do something do it, and those who don't know teach how to do it. But this man can hardly be blamed for being unaware of what he was doing when he jumped out of the window right in the middle of the lesson! Yes, your eyes don't betray you - this brave teacher was so inspired by his own lecture that all of a sudden he rushed to the window and dived out of it... Of course, the trick was quite unusual, but the kids will definitely remember the lesson for sure!
