Raj: Dude, there's so many cool things we could be doing tonight. Look. At the Glendale Galleria, "Put on your best zoot suit, it's a salute to Swing music in the center court near Macy's. 5pm to 9pm", huh, huh? A salute to zoot. Sounds like a hoot.
Sheldon: I'm sorry, Raj, I have no desire to salute any article of clothing tonight. Much less one that's linked to race riots in the 1940s.
Raj: Race riots?
Sheldon: The zoot suit riots.
Raj: Oh. I always thought that was some sort of after-Christmas sale.

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.

Raj: You can't wear the hands on the date.
Sheldon: Hulk sad!

Penny: You know, I believe in ghosts, too.
Leonard: Great.
Penny: And astrology.
Leonard: I know, and pyramid power and healing crystals.
Penny: Oh, no, no, no, crystals don’t work.
Leonard: Really, that’s the line? Psychics are real, but crystals are voodoo?
Penny: Oh, Voodoo is real. You don't want to mess with Voodoo.

Leonard: How can I go out with a woman who believes in psychics?
Howard: Hey, I once dated a girl who believed she was abducted by aliens.
Leonard: And that didn't bother you?
Howard: Au contraire. It meant that she was gullible and open to a little probing.
