Um. *shuffles feet* I don't know the first thing about human businesses. I already turned down the opportunity to run a kingdom: running my own family was difficult enough.

No, I would assume that the board of directors already know what they're doing, I'd tell them to carry on doing exactly that, and I'd walk away with the paycheck for one day's salary plus dividends in my pocket.
