Say: "Behave yourself!"
When R2 gets in a bad mood, his mood status indicator light turns red and he may not respond to your commands. This command will put him back in a content mood!
Say: "Timeout!"
And he’ll turn away, find the corner of the room and stand there like he’s in trouble! (When he does this, R2 may complain just a bit, or sneak a peek over his shoulder. But when he’s finished complaining, he will go to sleep.) Since R2 does not like being "punished," he usually refuses to move at first (by shaking his head). However, you can make him obey by saying "Behave yourself!" and repeating "Timeout!"
Say: "Do you remember…?"
And then wait for R2 to acknowledge your question with a beep. Then ask him about any of these famous friends (or enemies):
∑…Luke Skywalker?∑ …Anakin?∑
Every name will provoke a different response depending on how R2 feels about that particular character! Be sure to speak slowly and clearly and pause between your commands.
Say: "Re-set system!"
R2 will return to the beginning of his Companion Mode.
