I liked this episode, Christmas episodes are always my favorite in shows. You were right about the guy being "Santa" was too childish for the show, but after them explaining why he believed he was Santa made it way more understandable and better for the episode. I was right with you about the test results about the boy, I got why the dad ripped it up at the end of the episode, but I still wanted to know as well. For me it would have been interesting if we learned the little boy wasn't his, but the dad still loved and wanted him regardless. Great reaction!!
