Ah, I heard about this in Missy's interview (well, one of her interviews). Anyhows, the basis of the game is to take a shot everytime Lex touches his wang. Apparently he just can't help himself ... and gives his friend a tug now and then during his matches.
I am pleasantly surprised that they finally rewarded Kane with a long title run. Kudos to Undertaker to return the favour in doing the jobs. This just makes me very happy, and I don't even know why exactly.
