When I worked at BIW there were possums.

One died in a wall of the bathroom and nobody would believe the smell was a DEAD ANIMAL. The area manager or whatever came to check it out and, of course, someone had not flushed the toilet and left a giant steaming shit. He flushed it and said, well there's your problem right there, and walked out.

His face was much different as the fire department pulled a dead possum from the wall a week later.

(Despite my efforts, I was never able to catch a possum, and one guy found 3 baby ones in his hardhat)
