Sheldon: I shower twice a day and wash my hands as often as I can.
Lalita: Really? So do I!
Raj: But, you're a dentist, he's nuts!

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.

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.

Leonard: I don't believe it. What's gotten into him?
Penny: Oh, maybe a couple of virgin Cuba Libres that turned out to be kinda slutty.
Leonard: You didn't.
Penny: Hey, you do your experiments, I do mine.

Raj: How can I be a gynaecologist? I can barely look a woman in the eye!

Sheldon: How often does one see a beloved fictional character come to life?
Wolowitz: Every year at ComiCon. Every day at Disneyland. You can hire Snow White to come to your house. Of course they prefer if you have a kid.
