Sheldon: If someone, and of course, we don't know who this would be, does ask where you've gone, what should I say?
Leonard: I don't know. Just tell them I went to the office.
Sheldon: Are you going to the office?
Leonard: No.
Sheldon: Then how can I say it convincingly?
Leonard: Just say, Leonard went to the office.
Sheldon: All right. Leonard went to (dramatically) the office.
Leonard: What is? No, not like that! Just, Leonard went to the office.
