Ever wondered how things would be like if Barney (Neil Patrick Harris) and Lily (Alyson Hannigan) hooked up and got married on How I Met Your Mother? Curious fans will finally find out tonight at 8pm in the sixth episode of the fifth season entitled "Bagpipes."
Barney and Robin (Cobie Smulders) certainly look like the perfect couple but their seemingly rock solid relationship gets shattered as they have their first official major fight. Evidently, Barney's know-it-all attitude gets him in trouble with Robin and they are now forced to ask Marshall (Jason Segel) and Lily for relationship advice.
Seeking Marshall and Lily's help, however, isn't that easy for Barney and Robin since Marshall and Lily, who are having a few stereotypical marital problems because Lily is forcing Marshall to do the dishes, don't live up to their idea of the "perfect couple" who doesn't fight.
Consequently, Barney describes two different scenarios--- one of which involves a sequence where Barney wonders what will happen if he is Lily's husband instead of Marshall. In his "blissful married life" with Lily, Barney lays down the law on not having to clean and the couple shares a kiss.
