Sheldon Cooper:
Yes?

Leonard:
I'm Leonard Hofstadter. I called you about the apartment and you said to come by...

Sheldon Cooper:
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 Cooper:
You said you were a scientist. What is the sixth noble gas?

Leonard:
Radon?

Sheldon Cooper:
Are you asking me or telling me?

Leonard:
Telling you?

[Sheldon glares at him]

Leonard:
Telling you.

Sheldon Cooper:
All right. Next question. Kirk or Picard?

Leonard:
That's tricky... Original Series over Next Generation, but Picard over Kirk.

Sheldon Cooper:
Correct. You have passed the first barrier to roommatehood. You may enter.
