Isn't that stupid, ah?

Give me a card deck and I'll show you something you will never been able to explain. It will be your deck, you will control it (hold in your hands, shuffle it etc). You will imagine some card in your head and I'll show it to you. Magic? Mathematics? Card counting (ah, I won't even watch when you shuffle 'em)? Long sleeves? No, I will do it in a t-shirt or even w/o it (as you want).

The answer is: manipulation. Not a manipulation with cards. A manipulation with your mind. You will think that you control everything, that you imagine the card etc, but in fact, you will do what I want. So all these Monty Hall tricks are too lame for me. When you see 3 doors, I see only two of them and I do count the expected value (which actually can be "calculated" even by a little kid). Maybe that's why I've decided to be a coder? ;)
