Big Bang Theory Quote
Penny: What're you working on?
Sheldon: Can't talk. In the zone.
Penny: (to Amy) Do you know what he's doing?
Amy: Could be anything. Last time he was like this he figured out electron transport in graphene. Time before that he was making a list of who's allowed in his tree fort if he ever gets one. Still can't believe I didn't make the cut.
Penny: Uh, Sheldon, you wanna take a break? Your food's ready.
Leonard: Eh, what are you doing? He's both happy and quiet. Like seeing a unicorn and Bigfoot at the same time.
