Hmm, I can just imagine the sorts of challenges they will come up with to try and top last years.
Nude Limbo
Name the housmate by groping genitals while your blindfolded
Pin the Penis on the transgendered housmate
Russian Rulette (If only

)
Last man standing (Last one to pass out from alcohol poisoning wins)
I would also imagine things like enforced drinking for a day, or confiscation of clothing as possible punishments, pureley in the interest of ratings ofcourse as we know these are the only things that people watch for.
