Buffet is a bigamist. By all intents and purposes he lived with two wives. The legal status was not that of bigamy, to be clear. He married his other wife after his first wife died.

The personal section here is not exactly false, but is a great example of how one should not trust Wikipedia outright. A careful reading of it shows his lifelong relationships/marriage with two women at the same time.

Look, I'm not going to yuck his yum. Do whatever you want man. But the homely aww shucks image is very intentional. And very much against his actual life choices. Homespun he ain't.
