Last night just before going to bed, I hit stop on my bread machine and took the loaf out to cool. Then I hit stop, so that the machine wouldn't keep beeping at me as it finished its cool cycle. For those of you scoring at home, that is two hits on the stop button, which doubles as the start button.
Sooooo, it went through a second bake cycle while empty, and melted a huge hole in the top window. No more bread machine.
