I was crying too and felt rather silly for doing it but that's the mark of a really good show. The ability to make you cry when you really don't want to. I actually felt for both dad's in that situation. The one who did the switching and the one who was hurting so much that he couldn't let himself show it.
Powerful show and a great balance of humor and drama. Easily becoming one of my favorite shows of the season (it and Dirty Sexy Money)
