I recently watched this episode again and it is still just as touching. Earlier episodes in the season had been goofy and uneven, but this episode brought everything back that I loved about this show. Recognized or not Marshall is the backbone of the show, and his emotional roller-coaster and everyone being there for him was touching. His expectation that everything is going to be OK even at his fathers funeral. Spoiler*********
Even the ending where he gets pocket dialed and thinks his father has abandoned him only to find that final voice-mail. A beautiful ending.
