Big Bang Theory Quote
Sheldon: Yes?
Leonard: I'm Leonard Hofstadter. I called you about the apartment and you said to come by...
Sheldon: I know what I said. I know what you said. I know what my mother said on March 5, 1992. What is the sixth noble gas?
Leonard: What?
Sheldon: You said you were a scientist. What is the sixth noble gas?
Leonard: Radon?
Sheldon: Are you asking me or telling me?
Leonard: Telling you?
(Sheldon glares at him)
Leonard: Telling you.
Sheldon: All right. Next question. Kirk or Picard?
Leonard: That's tricky... Original Series over Next Generation, but Picard over Kirk.
Sheldon: Correct. You have passed the first barrier to roommatehood. You may enter.
