Summary: Filler Nothing of importance in this episode. I don't think I even laughed once. Normally, I see posts about how awful recent episodes are and I think that they really aren't that bad. This one certainly was. The Barney storyline of going to Canada to interview boyfriends was way out of character. The stalker thing was ridiculous. The whole episode was abysmal, in my opinion. Show us the mother already and lets get on with romancing her until the series finale. Stop with the filler episodes already.... sigh.
