Nailed it... totally obvious choice for Raj's girlfriend. I mean cmon, whos the no.1 quirky comedienne nowadays with the right age compared to other cast members, and doesnt have a regular appearance/role in other tv-series, answer miss kate ukulele playing miccuci. Whats next im horribly amused and ever so slighty scared.

I love it that Leonard told Penney that she will be responsible for announcing their engageent. Also Raj met a girl! Sheldon still doesnt get Amy anything nice for V-day.
