I've been a big fan of Mike Rowe's for many years now, and he seems like a pretty decent, down to Earth guy. He'd be a great Briefer (hint-hint Mike). I have my Amazon "Smile" set up to donate a portion of all my eligible Amazon purchases to his foundation, "MikeRoweWorks." The foundation funds scholarships for kids who want to go to a Vocational School to learn a Trade, and they win them by writing Mike and making a case for themselves.
More can be read about his foundation here:
