Raj: (fanning himself) Oh, this heat is brutal!
Sheldon: As someone from the tropical sub-continent of India, you should know that fanning yourself in a humid environment only raises your body temperature.
Raj: Huh. That does explain why the servants used to look so hot while they were fanning me.

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: Amy, good luck getting these guys excited about a dinner with a theme. I gave up when no one cared about my Tom Hanks-Giving.

Sheldon: Are they making fun of us?
Raj: Yep.
Sheldon: I miss the old days when I couldn't tell.

Bernadette: Speaking of new careers, how are things going with dark matter, Sheldon?
Sheldon: Oh, I have to say it's the most exciting time in the history of the field.
Bernadette: Oh, what's going on?
Sheldon: I started doing it.

Raj: You call yourself a friend? I was trying to help you. And at the first sign of trouble you ran away, leaving me to fend off a family of rats! You're a completely selfish human being and a physical & moral coward.
Sheldon: His statements of the obvious continue to annoy.
