I'll share a story for fun (no animals were intentionally hurt in this story)-
My Dad bought my grandmother a no stick pan as a present.
One day while we were visiting, she decided to cook us something, but, forgot to turn the heat off. The pan just sat on the burner.
We didn't really smell anything, but my grandmother's canary died, and we all had severe headaches later. I think it docked us all several IQ points.
