There was once a late evening I was very *very* tired, so much so that when setting up the coffee maker for the morning, I began pouring the full carafe of water into the electric coffee grinder, while it was plugged in.
It's a wonder I didn't electrocute myself, but I didn't. For even more of a wonder, the coffee grinder survived, once I had taken it apart to dry out completely and then reassembled it. It was never the same though.
