Raj: He doesn't just look like C-3PO, now he walks like him.

Raj: Oh man, first monster I see I'm gonna sneak up behind him, whip out my wand and shoot my magic all over his ass!
Stuart: Do you hear yourself when you say these things?

Raj: Doesn't anyone have a rod of resurrection? Because if you've got one, I need it bad. Get in here with your rod and give it to me.
Stuart: Okay, you need to say these things in your head before you say them out loud.

Raj: Okay, here we go. [to Leonard & Penny] Say cheese. [to Sheldon & Amy] Say cheese. [to Howard & Bernadette] Say cousin.

Howard: What do you think?
Barry Kripke: That ... is ... hilarious! Give me the remote control. I want to drive him into the girls' restroom.
Howard: All right, we're done. It's offensive.

Amy: Bert is studying the way microbes in rocks can survive in extreme environmental conditions.
Leonard: They say it could be a potential indicator of life on other planets.
Penny: You know what, I've met Bert. Isn't he an indicator of life on other planets?
Sheldon: You used to make those jokes about me. Now everything's Bert, Bert, Bert.

Raj: Well, I'm glad to see you moving forward.
Sheldon: Bert did quality research. And he deserves whatever accolades he receives.
Howard: What is going on? (To Leonard) Did you upgrade his software last night?
Leonard: I think he might be learning on his own.
Raj: Then the robot uprising has begun.
