Since we are all huge fans of C-diff and the smell of it, let me tell you a funny story.
I was working at a VA hospital in Madison, WI years ago and left a stool sample on the nurses station. It was liquid and looked like Campbell's beef & barley soup. After about ten minutes, I heard yelling. No... screaming! It sounded horrific, and reminded me of combat in Baghdad.
The old screwed-shut plastic cup exploded, covering the nurses station (computers, charts, a crockpot full of chili and a whole pizza) and several nurses with C-diff poo. They were so pissed off. I bet it still stinks over 15 years later.
