Shout "you lost the game" as loud as you can
pretty simple, yet admirable - you dont know who will hear/see...
We all know about "The Game" (if not check the pic) so why not go to a crowded public place where you would suspect that other people are playing "The Game" and shout out how you just lost "The Game". P.S. You all just lost the game!
Walk around your local town with your mobile phone against your ear. Shout at the top of your voice such as "No mum I am not having sex with a llama!" :P Do it...if you dare ;)
