[i really hope this hasn't been mentioned before, i searched for it just to be sure!]
i LOVE theme parties. the weirder the theme the better. so what if we had a challenge for the best theme party? submissions would be judged on originality of the theme itself and execution of decorations, costumes, food, whatever! can you imagine a more fun challenge to participate in?
this challenge may not be for now [with so many holiday obligations], but it would be great in, say, january or march... two of the most boring months, as far as i'm concerned!
