[Niles hired a private investigator to check Sherry out]

Dr. Niles Crane:
I was just looking out for Dad here. I mean, what do we really know about this woman?

Frasier:
She makes Dad happy, that's all we need to know.

Dr. Niles Crane:
Is it? Some people do get married before they know all they should. Remember Cousin Donald? He was married two years before he found out his wife used to be a man.

Frasier:
Yes, well, Cousin Donald is a very rare case. First, most people don't have a hidden past; and second, most people have a better eye for details than Cousin Donald. For God's sake, the woman could pick up a watermelon with one hand!
