Seen Any of These on Your Trade Show Floor Lately?

I saw this amazing list of talent for hire for trade show booths from Judy Venn & Associates on BoingBoing, and, thinking of all the roving talent I've seen at shows this year outside of the expo floor, from walking tree-people to human kaleidoscopes (it took us hours to figure out that's what they were supposed to be) to hallway Zumba instructors, I thought, well, why not belly dancers and computer skills teachers and yo-yo specialists? Anything on the list that sparks a creative idea for bringing your meeting's theme to life?
