I have never had a formal physics lesson in my life. I have however had some practical applications on occasion. I have fallen down before and have proven the theory of gravity. I have also been struck in the head with an apple, but it was only because my buddy Matt was proving a point at the time and he had no interest in theories, despite the orchard we found ourselves in. I have fired several firearms and shot a fair amount of pool, so while I have no formal education in physics, I do have a passing familiarity.
That being said, in my amateur "expert" status, this guy is a flipping genius!
I'm considering stealing his act and going on the road, but it will take me a while to grow the mustache and I'm trying to quit smoking.
