So walking the dog is no longer a cool Yo-Yo trick?

The world of competitive yo-yoing is a wondrous, mystical place — and for the second straight year champion Evan Nagao has blown our mind with “Freebird.”

Nagao was named U.S. champion for the second time in two years, and he performing a routine to “Freebird” both times. We first saw Nagao’s routine last year, and since then I’ve been obsessed with watching his astounding ability.
