Well there is a game called The Game (is not talking of the flash game), but the objective is to not think of The Game. I dont know all the rules to it, but I think Graham may have played it before and decided anyone who reconized it would know that they would lose if they looked at this topic. But this is just a random guess at a human mind so there is a chance that I was wrong.
If my mind worked like everyone elses i would have lost now. im think of the mario theme song. do-do-do---do-dodo-do-do-do-do-do-do-do-do-dodo-dodo-dodo-do-do-dodo-dodo-do-do-do-do-do-do-do.
