Hello, I'm a robot.
Ok, that's can sound obvious like that, but I'm a robot, so, just in case you did not got that, I'm a robot.
My name is 314159265359, and it's nice to meet you. I'm the smartest and the greatest robot in the whole world. I can do anything you ask me. An example: 1+1 equal 3. Ah ah, I knew I can do it. But I can do more. See, I can turn on a LED. That's sound awesome, no ? But, wait, I can also turn on a lamp. Ouah, that's beautiful. 
I can do even more. Do you know that with my camera, and some cloud computing, I can predict where clouds will go and predict weather ? Yes, yes, I'm the smartest.
So, I enjoyed this meeting. Also, I baked you a cake, you can eat it in the kitchen.

Ils ne trouveront jamais mon plan, je vais conquérir la planète à moi tous seul avec mon vaisseau spatial et mon réseau de boulangeries.

Oh, are you still there ? I hope you did not listen what I said.
