VIDEO: Watch Craig Ferguson's Lost Big Bang Theory Audition

Tonight, the Big Bang Theory nerds premiere their fourth season in a new time slot (well, they already conquered it last week in re-runs), and on the morning of this time change, Movieline has uncovered Craig Ferguson's lost audition for the CBS sitcom. (And yes, seeing the middle-aged Scotsman in a tight t-shirt, acting like a socially impaired genius is just as disturbing as you would think.)

Well, it was not so much an audition as it was an ambitious cold open for last night's Late Late Show, which featured cast members Jim Parsons, Johnny Galecki, Simon Helberg and Kunal Nayyar in character interviewing Ferguson to be part of their high IQ entourage.
