Redux: Worst Smell? Deer Head Left In Trunk

re: Thursday Question: What is the worst smell that you’ve ever smelled?

My cousin forgot to deliver a boxed up dead deer head to the taxidermist one winter- just left it in his trunk. Come spring, no one could stand to ride in the car, and he tried cleaning it and airing it out repeatedly, but neglected to check the very back of the trunk. After finding maggots meandering around the backseat and rear floorboards, he finally ripped the car apart and got a clue. But omigosh, what a stench/ Kendrama .

Question: Any others?
