Without the medical report...
I could see slicing open the scrotum and getting an unplanned vasectomy on a shard of broken porcelain would have an effect. Or... Getting a shard up the rectum would not be fun.
Right? I think these are the kind of injuries that are possible from broken porcelain. From what I’ve heard, the porcelain is so sharp that it slices right through arteries and people have actually bled out before medical help arrived.
I will never mess around with a cracked toilet, believe me.
