This episode was pretty boring. I know a lot of people will disagree. But, there were only a couple of things that were mildly amusing in this episode--Marshall's funk band and the idea that Marshall and Lily think Barney and Ted would be cute together (heh.)
Nothing happened. It was filler. And with the Robin/Don relationship needing to find closure--last season, this supposedly strong love affair between Don and Robin was all talk and no show. I still have no idea why we should have even cared about Robin/Don because were weren't shown anything.
So, is Ted going back to being an architect? It feels like the writers can't make up their minds. I guess we were supposed to be moved, but I wasn't.
This episode was not nearly as good as the last two episodes were.
