They should have given him something out of the trash.
Back in the day that would have been easy. Anything that died from overexposure to the heat lamps was placed a separate trash can to be inventoried later.
Knowing this, a couple of friends and I went through the trash at a local McDonald's one Halloween. If you knead a Bic Mac a bit, it turns into a gob of goo. Splatter one of those on a car windshield instead of an egg. It looks like someone threw up on it.
Unfortunately, that would likely result in a major lawsuit and the OWS protester suing, would get his wish of never having to work again.
It must be costing McDonald’s a mint in toilet water. It could be cheaper just to shut the place down until the OWS protesters go away.
