I really did like that episode, though I think that season might be my least favorite. You're right, the season did have some good episodes but I guess it's just the overall feel of the season I didn't like. It's weird, some of the individual episodes in the season I might consider to be some of my favorites, but the season itself, I'm just like, "Meh."
But yeah, that episode was really amazing. For some reason, once in a while for no reason at all, I get the image in my mind of Riley as a cowboy saying, "I'm looking for a man...a salesman." And in school, when we were reading Death of a Salesman, I was never able to take it seriously due to that. XD
Edit:
OH, AND WHO COULD FORGET THE CHEESE MAN? Hahaha.
