The episode opened stong with some side splittingly good one-liners. I think the writers strike has caused the writers to be more inspired with what they say which is great. The middle part of the episode is split between what Marshall, Lily and Robyn are doing and with what Ted and Barney are up to. The episode continues in true How I Met Your Mother style except that were focused more on the goal of the series more than in any other episode.
That's right. I mean the YELLOW UMBRELLA!
Not a lot is revealed about the umbrella toting girl but i think she was the one who bumps in to Ted whilst he is at the bar.
Overall the episode is extremely funny and well worth the 30 minutes. However the new development with the umbrella is making me feel that they may be bringing the series to a close which would be a HORRIBLE idea!
