Luke Skywalker: 3PO, tell them if they don’t do as you wish, you’ll become angry and use your magic.

C-3PO: But, Master Luke, what magic? I couldn’t possibly.

Luke Skywalker: Just tell them.

C-3PO: (C-3PO speaks to Ewoks…) You see, Master Luke? They didn’t believe me, just as I said they wouldn’t. (Luke makes C-3PO float) Wait, wait. Put me down! Help! Somebody! Somebody, help! Master Luke! R2, R2, quickly! Thank goodness.

Luke Skywalker: Thanks, 3PO.

C-3PO: I never knew I had it in me.
