Put some motorcycle stickers on walkers for a bunch of 45+ year olds n who did a dance routine to "Born to be Bad" and "Low Rider". They all came on stage with these walkers, robes, and hair in curlers hobbling like grannies. The music started they stripped their robes and started dancing in their bathing suite. It was hilarious.
Also did a colour change on a set of dance shoes once. The owner of the shoes forgot the black jazz shoes and we had brown ones. So we wrapped them black stuck so good, I think they are still black. Blow dryers are an amazing tool.
