Sheldon Cooper : [sneaking up to a house] I don't understand what we're doing.
James Earl Jones : Shhhh!
Sheldon Cooper : Whose house is this?
James Earl Jones : Carrie Fisher. And she's a little crazy, so get ready to run.
[he rings the doorbell, and they run for it]
Carrie Fisher : [storms out with a baseball bat] It's not funny anymore, James!
James Earl Jones : Then why am I laughing?
