That guy is blind, he can't see the twister, that's why he's carrying on as if nothing's wrong. How do i know? Because he's wearing black glasses (can't be sunglasses because it's not sunny!) And the biggest giveaway that he can't see is the fact that he's heading straight for that tree!! Haha. If he's not blind? Well there's only one other explanation and that is he's absolutely puddled!
