The following really happened...

Rock, Paper, Death...err...scissors

So there is this little game, you choose rock, paper, or scissors then type in your e-mail and your opponents.  The e-mail goes to your opponent saying they have been challenged and contains a link to an answer page, where they then choose rock, paper or scissors.  Then it says if he wins or not and the results are sent back to you.

 

I sent Light08 a challenge.  I chose Rock, I was very very clever.
He sent a message back saying:

Hah! i know that you wouldnt pick rock, and you knew i would think that,
but you thought i would be clever, and that i would think you picked paper
because it is the meekest, and who would pick it? and since you knew i would
think you picked paper, i would pick scissors, so you did pick rock, but my
friend told me you knew i would know that i was going to be clever, so he
told me you would have picked scissors, which is bloody obvious now that he
has told me, and thus you die, because i pick rock, loser!

The result came in right after that: "The battle ends in a tie. Reissue a challenge to continue."  It seems he chose rock also.

I sent him a message:

Not as clever as we think eh?  I knew you would think that I wouldn't pick
rock because it is the usual obvious choice.  So I knew you would think I
picked paper because it beats rock, but I knew that you would think that I
picked paper, so you would try scissors.  I knew that you would know that I
would know that you would pick paper because I knew that I would never
choose rock unless to fool you, which you knew, so was going to pick paper,
but I knew that you would know I would.  I thought you would know that I
would choose paper, so I chose rock because I knew you would not know that I
knew you would not be paper.  I knew you would think I was paper or scissors
so you would choose scissors or rock to win, that way, no matter which you
choose I win or it is a tie, but I never thought that maybe you knew that,
but you didn't.
lets never play this fowl game again.

He sent a challange.  Saying "I guess i was wrong". At the end of it.

I sent him a letter:

lets see, I picked rock last time, so you know I won't pick it again, unless
I am clever, so I will, but you know I will, and you will pick paper, but
you know that I will know that you will pick paper so you will pick rock
again because you think that I will pick scissors to beat your paper.  But
you cannot be sure I won't know this and pick paper to beat your rock.  So
you think I will be rock or scissors, and the only way to win would then to
be paper or rock, and the only thing that neither paper nor rock can beat,
is paper!  So I will not do what you thought I would do because I knew you
knew I would know that I would pick what I thought you would not know.

I went to the site, and chose paper, and he threw a rock like I knew he would, and I won.
Now I know, that rock, paper, scissors is the most complicated game ever made!

He sent a message back saying:

argghhh! you outsmarted me!! bastard!!!!!!!

i actually picked rock because i thought you would
pick scissors, because i knew you would think that i
would think you were going to go only for paper or
rock, and since you thought i was only going to be
thinking you could choose between those two, i thought
you would think that i was going to be scissors, and
that you could also pick scissors or rock, but i
thought that you would think i had already thought of
that so you would pick scissors because i was
expecting rock because you did that last time and who
would do it again right? so then i thought you would
pick scissors because you thought i had gone paper,
because you were going to pick rock, to be very
clever, but i knew you wouldnt, so i picked rock to
beat the scissors because i thought you would think i
had picked paper, or scissors also
but it looks like i outhought myself, and you
outhought me, i yield in defeat.

You can pretty much guess that we know each others minds very well.  So well, that It takes a long long time to play a simple game like rock, paper, scissors.
