World's Greatest Couple

I like the bit where he said yesss when asked if it was his wife

Another great episode of "How I Met Your Mother" that features Barney Stinson in it's main story. Neil Patrick Harris is a joy to watch Every time there is a great episode of this show, it's him that is the focal point.

Plot In A Paragraph: Lily (Alyson Hannigan) is introduced to Barney's (Neil Patrick Harris) batchelor pad "The Fortress Of Barnitude" when she urgently needs a place to stay. It's only meant to be temporary "two nights" but when he realises he can use Lily as a fake wife to scare off one night stands he tells her she is never leaving. Meanwhile Marshall (Jason Segel) finds a new friend to go to concerts, musicals and brunch with.

Cobie Smulders and Josh Radnor don't really have anything to do here, but that's OK because the Jason Segel story is fun and he always delivers.

but again this episode belongs to Neil Patrick Harris and Alyson Hannigan. Their scenes together are an absolute delight.
