Rainn Wilson, the actor best known for portraying beet farmer and assistant (to the) regional manager Dwight Schrute on NBC's The Office, has given St. Petersburg's Overflow Brewing Company a big hand promoting an upcoming event and beer release.

Wilson appeared in a video posted to Overflow's Facebook page Thursday to address "Floridians of St. Petersburg and beyond," and tell them about the downtown brewery's The Office trivia nights on Oct. 3 and 17, featuring a special beet beer called My Diabolical Plan that Overflow has brewed just for the occasion. (Wilson himself doesn't drink, but his assistant Matt tried some My Diabolical Plan on-camera and said, "It's very good.")

In the video, Wilson said the brewery would be giving away Office swag signed by him "and maybe others."

"You know what that means, time to start re-watching all nine seasons of The Office," Wilson says in the video.

"You know what the best part of all of this is, why I'm even involved in this at all? A portion of the proceeds ... go to helping educate young girls in rural Haiti."

Wilson is one of the founders of Lide Haiti, a charity that uses the arts and literacy to empower at-risk adolescent girls in the Caribbean country.

The Office Trivia at Overflow! More details will be released tomorrow. But for now, watch this video!
