An okay episode. When Marshall and Ted shook hands, I got so excited for the return of THE SLAP BET!!! But wtf, it was over too quickly and it didn't involve Barney, which meant it wasn't as good. Old couple bagpiping was awesome. I loved Barney picturing himself how him being in a relationship with Lily would turn out. And for the first time this season, Robin/Barney combo didn't bother me too much.
