One of the worst episodes ever !!! They made us wait for one full month to give this nonsensical stuff. The slap, they just spoiled the entire essence of it. Where did the writer come up with totally random stuff like the "One Year in China" thing!? Its disappointing that HIMYM, which has been such an awesome series till last year, has to resort to such pathetic filler episodes!! Maybe this is what happens when you run a series a bit too long. You run out of ideas !! And you just wanna take it to "The End" somehow, even it means spoiling the reputation you made up all these years !! Sorry Season 9, but you have been way below expectations, but still I will be watching you just for the sake of getting done with it!!
