Although not directly poo related here is one of my life's grossest moments...
In my early twenties I managed a McDonald's restaurant.
I got the message that the ladies turlet was plugged. Dutifully I grabbed the plunger and headed in. The bowl contained the foulest stew I had ever seen. The water was blood red, there where cigarette butts, a kotex (or something like it, didn't examine it for a brand name) and several floating turds.
Disgustedly I aimed my plunger and started to work on the clog, she wouldn't move. I ponied up and increased the vigor of my strokes. Kasploosh, a gusher!! With the extra effort exerted the bloody stew backfires and soaks my face and shirt.
When I plunge now, I do so with great care.
