I turned up around 6 to help set up. I walked into the theatre as normal and there were all my coworkers.
One dressed as a panda and the rest as giant Fruit-of-the-Loom style berries.
As soon as they saw me, they let out a great cry:
"ghost_light is here! ghost_light can be the other blueberry!"
And I was immediately hustled into a giant Mossberry costume.
There was one coworker and one costume left - Oompa Loompa. She correctly identified the fruit was much less silly and exercised her 'I was here first' rights to reclaim the Berry costume.
But I was a cute Oomp Loompa, dammit.
