I just came back from RainFurrest in Seattle, WA. They had an interesting event there: a pet auction. Those who were willing would sign themselves up to be auctioned off as a pet. That person would then have to accompany the winning bidder around as their pet for a given amount of time during the con, though the pet was in no obligation to do anything as a pet beyond what they were willing to do. Each pet would have a "bio sheet" with info about them (i.e. likes, dislikes, etc.).
Has anybody thought of conducting a pet auction at MFF?
