Former UFC welterweight champion Georges St-Pierre never stops his pursuit of Martial Arts knowledge. While on vacation in Los Angeles, the MMA legend was humbled, and schooled, as he admits through instagram.

I got schooled today at Renzo Gracie Academy LA by my friend @ShawnWilliamsbjj who I like to call “My worst nightmare” lol. It was a humbling experience and a lot of fun.
