Where's Surly? In that big drain in the sky?
I liked the idea of Surly BB2012 (not that he kept dying and being replaced) that he got HM's doing kind of naughty things but last year Surly was lame and just didn't work. Why not just a evil BB instead - a voice completely different from the normal BB's. Could go something like this - Normal BB calls a HM to a darken Diary Room then evil BB talks and gives a task a HM's do naughty things (nothing to naughty just a bit of fun) with a reward at the end if task is completed but whatever the task the other HM's can never find out or it's automatic up for eviction for HM with the task whether they take the task or not. Could work.
