Not necessarily everybody: if you try hard and have talent for fake mannerisms, you could conceivably fool people... although trying that hard to act differently so well doesn't actually sound real fun to me.
Thanks; I thought that would sound funny. But, really, applauding a most creative theme is a fair idea, I think. Dunno about an actual poll... if we could just get everyone to gather in one thread by pre-planned announcements and such next year, however, and motivate talk about what each "wore" and whose choices seemed especially worthwhile, it's likely some consensus would emerge. Of a rough sort, anyway. But rough consensus might be good enough... unless you want to give out some kind of actual prize. For simply encouraging better efforts, though, all we probably need to do is to say matter-of-factly, "We're all really interested this year to see each other's best efforts."
