Earlier this week, we brought you a video of a physics teacher who, in an attempt to make his class more interesting, ended up getting his testicles smashed with an axe.
That was an example of someone completely failing to impress his students. This video, on the other hand, is an example of someone who has 100 percent succeeded at it.
Math is obviously the most boring subject ever, and lectures are the most boring way to learn. So when this teacher suddenly starts interacting with his virtual double, these kids understandably lose it.
It's even funnier when you imagine him rehearsing this in the lecture hall alone, again and again, until he had it down.
That, boys and girls, is dedication.
