Usually cold-hearted Robin is in tears over the news that her mother will not be attending the wedding. In trying to make Robin feel better, Ted, Barney and Lily each are brought back in their memory to a time six months earlier. Then, Lily noticed that the challenges that Barney always accepted in picking up women were those that he issued for himself. So Lily and Robin went on a quest to issue Barney challenges on picking up women that they believed he could not complete. This quest became an all night task. The one challenge that Barney felt like no challenge at all ended up being the most difficult not so much for the challenge itself, but for the advice he got in return. What Robin, Barney and Lily are and were unaware of is that at that same time, Marshall tried to convince Ted that, based on inside information, he should still try to pursue Robin, despite Ted vowing that their relationship was then purely platonic. Events, including a telephone call from Chicago, made Ted truly... Written by Huggo

Platonish (#9.9)
11 August 2015 | by (Canada) – See all my reviews

The good part about this episode is to go back into the good old times. Even though I liked the show how it is going, I have to admit that I miss Barney when he was single.

And they bring us some great story of him accepting challenges from Lily and Robin. And those are pretty hilarious. Him getting a phone number when talking like a dolphin was hilarious.

And then we find out how he decided to stop playing the games but to win one, by getting together with Robin. And this is a great addition that makes the two of them together even sweeter. But I am not sure I like to see "mother" in it. I kind of find her character more and more boring and not interesting to spend time with.
