Normally, what makes this series so good is that it stays believable. in this case, I believed neither of the three stories. I don`t believe that a couple like Marshall and Lily wouldn`t able to live together for more than a few hours. I don`t believe that Robin and especially Ted would decide against living together with the moving truck in front of the door of the new house, just because they had a fun night without each other. And I really don`t believe that even somebody like Barney would hijack his friend`s moving truck to prevent him from moving together with the woman he loves.
Also, part of the fun of the series is how they mess with the time line. But they didn`t do that as much in this episode. As this is still my favorite tv series, I give it six points anyway.
