I think this episode was good and something you would appreciate if you watch more of this series (Season 6) The one bad part was the music in the club, but club music sucks anyway. I like that the women that Ted ended up with in this episode was not someone you expected. Too bad future Ted said he didn't end up the coat check girl. However, I have a theory (I have many on this show). Ted has been to a lot of clubs and why mention this one? Maybe the future wife worked as a coat check girl. Also good from the club scene was the nerdy guys.
The second part with Lilly and Marshall was also good. When they realize they think they need to grow up, I think it's funny how they struggle with it. One part of this episode, that I really like and something you will see more of from this show is how the truth gets stretch. I like that future Lilly and Marshall leave their party on the way they said it happened.
