I did a puppet show in a bar once; I was asked to sing at an Elvis Presley cover night, but I didn't feel like singing. So I took a frozen hamburger, put a styrofoam quiff on top of it and attached it to my hand with wire and did a puppet show of cc rider, with two hamburger boxes as back up singers. After the show I put the hamburger on a shelf above the bar. I forgot about it and left it there. A year later I remembered forgetting about it and called the owner of the bar; she checked and it was still there, no smell, no mould, not liquified, just hard as rock. Just like Elvis.

Looks like the old website for Chicks On Speed, so this is pretty avant garde, actually.
