The person you impersonated may sue you, I guess. You used his image to promote green beans without the right to do so. Normally that's something you pay for,

The person you impersonated may sue you, I guess. You used his image to promote green beans without the right to do so. Normally that's something you pay for, you didn't, and I guess he may ask for what the personality rights for such an ad would normally cost. And depending on how you done it, it could conceivably damage to his reputation, qualifying as defamation. I don't know, maybe he got in trouble with the red bean industry because of that. That's similar to violating a trademark.
