Ok, clarifications:
1) The farmer is married.
2) There are no cows on the farm. However, a portion of the grain will be fed to cows.
3) The farmer is not fat.
4) The hampster is fat, but will not be fed to any cows.
5) No, the farmer doesn't fertilze his fields with Cousin_Eddie.
6) No, the professor of African Studies does not have a Sociology degree. He has a Art Appreciation degree (which is far more useful).
