Melted board
Do you have someone in your family who seems to be intelligent, but who is always making the most idiotic mistakes? The one who trips over nothing, or always leaves the water running in the bathroom by mistake?
Or this guy, who seems to have forgotten that plastic melts, and so stovetops are not the place to leave chopping boards. At least he left an apologetic message before he drove off to Walmart to pick up another board.
