When I saw that baked potatoes were served I got the idea that it would be very good if I pretended I did not know what potatoes was. That would be funny.
Well let me tell you: backfired on my face. I'll tell you how.
So first when the potato became on my plate, I acted very interesting. I showed an expression on my face so as to seem that I was confused, astounded but in a restrained way, curious, and interested. They did notice, and seemed confused, but did not remark. So I asked "This looks very interesting. What is this?"
