Well it's over! The Big Bang Theory ended it's long run with their finale Thursday night. It was (and still is) one of my favorite shows of all time. There is just something about it that makes me smile every time I see it. And as luck would have it, one of my all time favorite bands "Barenaked Ladies" actually sung the theme song. So after the finale, the band stopped by the Late Show to perform the whole song. Yeah, they actually wrote an extended version of the song and it's so much fun to listen to that I had to share it with you!
