Zachary Levi: Short Shorts at the Teen Choice Awards!

Zachary Levi brings out his inner nerd on stage at the 2011 Teen Choice Awards on Sunday (August 7) at the Gibson Amphitheatre in Universal City, Calif.

The 30-year-old Chuck actor challenged host Kaley Cuoco to a game of ping pong during the show and showed up in his “nerd” outfit.

“I would love to wear pajamas every day of my life if I could. I don’t really believe in fashion so much. I’m a t-shirt and jeans guy,” Zachary shared on the red carpet about his sense of style.

Zachary also said that Luke Skywalker makes an appearance on Chuck‘s season premiere!
