The more things change, the more things get interesting in this all-new hilarious season of How I Met Your Mother. Ted's (Josh Radnor) search for "the one" continues while Marshall and Lily (Jason Segel and Alyson Hannigan) hope to become parents, Barney (Neil Patrick Harris) makes an uproariously awkward attempt to find his real father, and Robin (Cobie Smulders) finally feels like a true New Yorker. Featuring epic guest stars like Katy Perry and Jorge Garcia as "The Blitz," Season Six is filled with just plain awesomeness.
