Aww, what a cute way to celebrate The Big Bang Theory’s first Emmy nomination for best comedy. But that’s not why the Barenaked Ladies took a trip to the show’s Warner Bros. TV lot to shoot a full length version of the theme song. The video was actually made to help kick off the sitcom’s launch in syndication this fall (it will air five nights a week on TBS and stations across the country beginning Sept. 18).

A bit o’ history about the snappy tune in case you didn’t know: Theory creators Chuck Lorre and Bill Prady — who are fans of the band — asked Barenaked Ladies’ singer/guitarist Ed Robertson to pen a theme song for the sitcom as a “sort of history of everything … in about 32 seconds.” The rest, of course, is history.

Keep an eye out for Lorre picking the gee-tar.
