"Just A Wee Bit" joke

An extraordinarily handsome man felt he had the God-given responsibility to marry the perfect woman so they could produce children beyond comparison. With that as his mission, he began searching for the perfect woman. After a diligent, but fruitless, search throughout the east coast, he began to head west.
Soon thereafter, he met a farmer who had three gorgeous daughters that positively took his breath away. After explaining his mission to the farmer, he asked for permission to marry one of them.
The farmer simply replied, "They're all lookin' to get married, so you came to the right place. Look them over and choose the one you want."
The man dated the first daughter and the following day, the farmer asked the man for his opinion.
"Well," replied the man, "she's just a weeee bit, not that you can hardly notice, pigeon-toed."
The farmer nodded and suggested the man date one of the other girls, so the man went out with the second daughter.
The next day, the farmer again asked how things went.
"Well," the man replied, "she's just a weeee bit, not that you can hardly tell, cross-eyed."
The farmer nodded and suggested he date the third daughter to see if things might be better. So he did.
The following morning, the man rushed in and exclaimed, "She's perfect, absolutely perfect! She's the one I want to marry." So, they got married right away.
Several months later, the baby was born. When the man visited the nursey, he was horrified: the baby was the ugliest, most pathetic human imaginable. He rushed to his father-in-law and asked how such a thing could happen considering the parents.
"Well," the farmer calmly explained, "she was just a weeee bit, not that you could hardly tell, pregnant when you met her."
