Answer:
Who is the most foreign visitor you could imagine?
I can be simple or I can be complex. I can be found in this riddle or in everyday life. I can be shapes or even colors.
You throw away my outside you cook my inside. Then you eat my outside and you throw away my inside.
I stare at you, you stare at me.I have three eyes, yet can't see.Every time I blink, I give you commands.You do as you are told, with your feet and hands.What am I?
Of these things - I have two. One for me - and one for you. And when you ask about the price I simply smile and nod twice.
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
