@DrewDad,
Interesting. I'd consider myself average looking. My wife is quite pretty. Our kids are knockouts - all three, two girls and a boy.
There was a couple who had twin girls on my younger daughter's JV soccer team. They guy could have passed for Jim Palmer and his (ex) wife was about 6' tall, model thin, and gorgeous. Their two girls were about as ugly as the two of them could have possibly produced.
So, just sayin....
