Well, we know that the big wedding is just hours away, but this does not necessarily mean that a guest star won't be crashing to bring joy (and bad memories) to our characters. And yes! Gary Blauman (Taran Killam) is back and somehow some of our characters are not pleased to hear the news. Although Gary is one of Barney Stintson's co-workers and ultimate bro, the groom also shares the same pain everyone is experiencing by just simply recalling their personal encounters and experiences with Blauman. Nevertheless, the episode will surely be very interesting since in real-life, Killam is Cobie Smulder's hubby. So technically speaking, he will be there when his wife walks the aisle in the series. Catch the all-new episode this Monday night at 8/7c on CBS. Watch How I Met Your Mother season 9 episode 21 stream through the free online stream link found at the bottom.

There are only two episodes left before the two-part finale of the show, and everyone is very much excited over the much-anticipated finale for Ted and the Mother.

Additionally, we can't deny that ever since the final season began airing, many have been orchestrating theories on how the show ends. There is even a speculation that the mother is apparently dead all along and that the show creators were hinting her funeral when they said that the finale is going to be sad. But then again, everything is left vague until the final episode airs. Watch How I Met Your Mother season 9 episode 21 via online access using the free online stream link at the end of this post.
