You know, even just thinking about this episode makes me smile.  And honestly, it's really hard not to when you start hearing those opening notes to Pinkie's best song in the entire series.  And that's saying a lot, given the fact that Pinkie has been given quite a few moments in MLP to sing her heart out.  But this song...I don't care how bad of a day I've been having, listening to this happy tune just makes me Smile, Smile, Smile right along with everyone else.
