Robo-bath

Me (gathering towels after baths): Who has which towel?
Thing One: Mine is the frog and (Thing Two) has the duck.
Me (wrapping Thing Two in his towel): Come on, duck boy.
Thing Two: I. A. Ro. Bot. You. Call(ed). Me. Duck. Boy.

Robots

Thing One: I need to turn everyone who hasn't died into robots.
Me: Why?
Thing One: So they'll never die. Because robots don't die. Until the metal gets old.
