Sheldon: Is there some problem?
Leonard: Yeah. Listen, I have to kinda sneak out for a while.
Sheldon: All right, goodbye.
Leonard: No, wait. If anyone asks you where I went, you don't know.
Sheldon: Where are you going?
Leonard: I can't tell you that.
Sheldon: Who would ask me?
Leonard: I can't tell you that, either.
Sheldon: So you brought me in here to inform me that you can't tell me where you're going and you can't tell me who might ask?
Leonard: Yeah, I really didn't think this through.
