Penny: So, I was thinking how excited you get about stuff like Buffy or science or which TV remote you and Sheldon should buy.
Leonard: The Harmony One was fine. We didn't need to upgrade to the eleven hundred, which he knows is too big for my hand.

Leonard: What would you be if you were attached to another object by an inclined plane, wrapped helically around an axis?
Sheldon: Screwed?
Leonard: There you go.

Leonard: My point is, while you're spending all this time on your own, building computers or practicing your cello, what you're really doing is becoming interesting. When people finally do notice you, they're gonna find someone a lot cooler than they thought. And for those of you that were popular in high school, it's over, sorry. Thank you. Congratulations.

Leonard: [to a "smiling" Sheldon] We're here to see Koothrappali, not kill Batman.

Howard: People change names on blogs to protect their privacy. Roger is Raj.
Raj: Oh, I always thought if I had a white name it would be Gavin.

Sheldon: You don't know what it's like to feel completely frustrated. To have a desire build up within you and be denied any opportunity for release.
Amy: Yeah, sounds like a drag.

Amy: Missed one. Now your wish can't come true.
Sheldon: Lucky for you because I wished you were dead.
