Leonard: When are you going to stop making Cylon toast?
Sheldon: When I have enough to destroy all the human toast on the battlestar known as Galactica.

Sheldon: Is that what you're wearing to watch football at Penny's?
Leonard: What's wrong with a football jersey?
Sheldon: Nothing. That, however, appears to be a football cocktail dress.

Sheldon: Hold on I believe that social convention dictate you not arrive empty-handed. Would you like to bring some Cylon toast?
Leonard: Yeah, no, I'm trying to fit in, not get laughed at.
Sheldon: What's funny about Cylon toast?

Howard: I brought you a little gift. New kite.
Raj: The kite you made me lose was an authentic Patang, an Indian fighting kite that my brother sent to me from New Delhi. It took me a day to put together and two days to paint. This is Hello Kitty.
Howard: Yeah, but it comes with a little coin purse. Does a Patang?

Leonard: Go! Go! Go! Go, go, go, go! Yes! Are you people watching this? Is this amazing or what?
Penny: Sweetie, that's a highlight from the '98 championship game.
Leonard: Oh. Did not know that.
Penny: How much beer have you had?
Leonard: None. Why?
Penny: Oh. I was just kind of hoping you were drunk. Now we're back live.
Leonard: Okay, yeah. I can see the difference.

Sheldon: So Leonard, how goes the mimesis?
Leonard: Mimesis?
Sheldon: You know. Mimesis. An action in which the mimic takes on the properties of a specific object or organism. Mimesis.
Leonard: What the hell are you talking about?
Sheldon: I'm attempting to communicate with you without my meaning becoming apparent to those around you. Let me try again. Have the indigenous fauna accepted you as one of their own? Nudge, nudge, wink, wink.
