This episode of The Big Bang Theory was a little silly, but hey, sometimes that works. The quick look at Sheldon and Raj fighting was definitely funny in a quirky way.
Johnny Galecki, by now you know my feelings on this guy. Will Forte left SNL recently, they should just recast him in the role.
Sheldon was good with the limited work, and Howard was actually funny in a first real episode that revolved around him. Katee Sackhoff and George Takei were pretty forgettable though, and that scene with them in the back of the car was just absolutely nonsensical and pointless.
