answer:I did saw a “Life in the ER” episode where a guy got super, super, super sick and it took them forever to find out what the problem was. They finally traced it back to a bar-b-que he had attended. The host had cleaned the grill with a grill brush that used metal thingys for the brush. One of those thingys wound up in the sick guy’s hamburger and he ingested it. It punctured his intestine. What’s the moral here?
