It's always boggled me why whenever I encounter a robot and get into conversation with it long enough for it to get comfortable; it will have a tendency to say things twice. It will say stuff like "Affirmative Affirmative!" or "I want a cheese burger please, I want a cheese burger please" or "Ham Sandwich oooh, Ham Sandwich".
After much pondering I have come to the conclusion that Robots repeat themselves because the have a superiority complex. They feel that if they just say things once I would not understand what they are trying to say. They think I am too dumb to understand them the first time.
I wish I had a laser.
