WEEZER drummer Patrick Wilson pulled off a pretty SWEET move during their show in St. Augustine, Florida on Friday night.

In the middle of a song, a fan threw a FRISBEE up onstage, and Patrick caught it, while continuing to play.  In order to free up his hand, he put the Frisbee in his mouth ... until he had time to toss it aside.  (Here's video.)

The next day, Weezer singer Rivers Cuomo Tweeted, quote, "[That's] one more reason Patrick Wilson is my favorite drummer in the world."
