Somebody filled a trash bag full of sharp objects they were planning on throwing out, then decided "I can't just throw a bag of loose sharp objects in the dumpster. Oh, I know the perfect place for this! Dead center of the living room floor." I stepped on it in the pitch black of the night. Luckily I only hit the edge so I only injured a single toe, but I straight up ripped the flesh nearly from the bone of it. Even stupider, I didn't go to the hospital for it. At least until I had an appointment for something else anyway, at which point they saw it and immediately made me go to another doctor to get it addressed.
