Han: Let him have it. It’s not wise to upset a Wookiee.
C-3PO: But sir. Nobody worries about upsetting a droid.
Han: That’s cause a droid don’t pull people’s arms out of their sockets when they lose. Wookiees are known to do that.
C-3PO: I see your point, sir. I suggest a new strategy, R2. Let the Wookiee win.
