Silence of the Lamb
I was a carer. I once walked into a new client and the house stunk!!! The sink was full of black water so I plunged in to take the plug out and when it drained there was a decomposing lambs head.
As I stood shocked and disgusted that I had been elbow deep I turned around to find this old lady lighting paper on fire on the gas stove and she nearly blew us up! It was a long night. Story credit: Reddit / Echoda
