When the kids were young, my husband decided he would make cinnamon toast for breakfast. Me and the kids were in the living room, and suddenly we all started coughing, and our throats were burning. We had to open the door and go outside. I thought he had burned the toast in the broiler, but when I managed to go in and investigate, we realized he had grabbed the cayenne pepper instead of the cinnamon. That stuff will hurt you when it starts burning under a broiler.
