Well... it was similar to that...
I had eaten at a sushi place for lunch one day and had gotten some to go as I didn't have a lot of time to eat there and still had some leftovers that I intended to finish at work. I place them on the floor of my car, they slid underneath my car seat and I forgot about them.
A day later, I went to my car and of course smelled the smell of death coming from somewhere inside. A little searching around led me to the paperbag with the rotten, sun kissed sushi. Gagging/puking aside... it inspired me to make this thread.
Call it inspiration due to rot.
