BJ Penn knows what he wants to do with his life post-fighting career ... run the state of Hawaii, 'cause the UFC legend announced he's running for governor of The Aloha State!!!
42-year-old Penn -- a UFC Hall of Famer -- threw his hat in the proverbial ring (Octagon?) this week, and even laid out several policies he would immediately overturn.
"As soon as I step into Hawaii's Governor office I will remove all new federal and state mandates that have been hurting our economy, residents, and 'ohana," BJ wrote.
