Critics
"I very much like seeing the show bring back a couple of the arc plots in Bernadette and Raj and Sheldon working together. It rewards fans for paying attention and adds depth to the show...As for Howard, he needs Bernadette. I'm relieved to see her back because she seemed to have been written out of the show last season and she makes him a more likable character...I do appreciate the consistency of having Katee Sackhoff back and all credit to George Takei who camped the hell out of everything they asked of him...Two good stories but neither was well told." - The TV Critic's Review

Quotes
Raj: I'm telling you, if emits, then those  discoveries must be wrong!

Sheldon: Yes, well, if we lived in a world where slow moving Xenon produced light, then you'd be correct. Also, pigs would fly, my derriere would produce cotton candy, and the Phantom Menace would be a timeless classic.

Raj: You're so ! If you were a superhero, you're name would be Captain Arrogant. And you know what his superpower would be? Arrogance!

Sheldon: ''You're wrong again. If my superpower were arrogance, my name would be Doctor Arroganto.''

Sheldon: Penny, a moment.

Penny: What?

Sheldon: Nothing, I just wanted Raj to stop talking.

(Raj tries to whisper something to Howard)

Howard: (To Raj) No, no, he won, suck it up.

Sheldon: This isn't a desk, this is a Brobdingnagian monstrosity!

Raj: Is that the American idiom for "giant big-ass desk"?

Sheldon: It's actually British.

''Sheldon: Why do you even want this here? Its size is completely disproportionate to its purpose.''

Raj: Well seeing as its purpose was to piss you off, I'd say it's spot on.

''Sheldon: Alright, I see what's going on here. This is the opening salvo to what will be a escalating series of juvenile "tit for tat" exchanges. Well titted.''

Raj: Thank you.

Sheldon: Stand by for my upcoming tat!
