I'm not sure if you considered our performance, but here are some last minute ideas.
1. You can do a jig and toss tinsel about while I play the violin.
2. We cover ourselves in glitter glue and strip.
3. Hire strippers to cover themselves in glitter glue and strip.
4. Do you know how to make balloon animals?
5. We make like Sandra Bullock in Miss Congeniality with the water glasses (sparkley water). Not me on the female yodeling costume.
6. Decorate a lovely volunteer like a Christmas tree.
7. We could do an interpretive tango to "It's Raining Men" in sparkling suits.
8. Chocolate makes women swoon. We could throw Hershey kisses at people.
9. Freeze a kiddie pool and perform an ice dancing number.
10. None of these are serious ideas. I had been hoping you came up with something, because I forgot about this.
