If you thought all it took to wave "hello" was rocking your hand back and forth, you thought wrong. Depending on to whom you're waving, how you're feeling, your geography, and literally hundreds of other variables, your wave could take as many as a hundred shapes. But fear not! Our guy's gonna give you a hand.
Remember how you just watched a video about 100 ways to wave? We forgot -- there's one more. It involves churning water, hapless humans, and a severe inability to hang ten. Surf's up, but swim at your own risk.
