It's a few weeks before the wedding. In their continuing slap bet, Marshall wants the next slap he exacts on Barney to be the most painful thing that Barney has ever experienced. Marshall knows however that this threat means nothing to Barney as Barney is now immune to Marshall's constant taunting. Marshall, as such, proceeds to tell Barney a story of the extensive training he got from the masters of slaps to achieve his goal, that three part training which includes how to exact slaps of a combination of speed, strength and accuracy. Marshall not only has to convince Barney that he went through this training, but to convince Barney enough that Barney is once again traumatized by Marshall's constant taunting. Written by Huggo

Worst episode of HIMYM

It's ironic that the worst episode of the entire series is followed by one of the best episodes (How Your Mother Met Me). I really enjoyed the end, but i have to agree with those who say that the 9 season of this amazing show almost ruined the show itself. And it's so sad because a show its always remembered by its final season, in my point of view. It was a wasted episode. The authors should have used this time to show us a little more about the mother, a little more about her relationship with Ted. The criticism around the final episode is, at least the most part of it, around the short time of Mother's life on screen. In sum: unfunny, wasted time, boring episode.
