The Father Son Challenge

Apparently one of the rules of this even, broadcast on NBC this weekend, is that the father had to have won a Major Championship. Would they really tell Tiger Woods that he couldn't enter this event with his dad??? I think that's a stupid rule. Why does winning a major have to be a requirement? Fuzzy Zoeller played with his daughter, not a son. Should that be allowed?? I guess as long as he won a major, it's ok. You have to wonder why some rules are more important than others.
