Spoilers for 408 – Wooo!

Spoilers after the jump. [Also, another InFANity video has been added to the previous post.]

This episode finds Robin’s position as Lily’s best friend threatened by Jillian, a coworker of Lily’s. Lily brings Robin along to the cowboy-themed bar where Jillian is celebrating her birthday with some friends, only to discover that Jillian is a Woo Girl. [As Future Ted explains, Woo Girls are named for the distinctive sound they make to celebrate everything, from half-price shots to their favorite song coming on.] Turns out Lily feels the same way about Woo Girls that Ted does about New Jersey, but over the course of the night she finds herself starting to act like them.

Meanwhile, Goliath National Bank is looking to build a new headquarters, and Ted has submitted a design, which Barney enthusiastically backs – until he meets the other potential architects, a couple of guys named Sven who have designed the world’s most outlandishly awesome building, with special attention paid to Barney’s new office.
