I was trying to close a cupboard (at head height) with my bare foot as I had a just-boiled kettle full of water in one hand and a cup in the other. First attempt: Good - clipped it well but it wasn't quite shut, second attempt, I took a step forward and let fly - hit the work surface, at full force, cracked middle and 'ring' toe.
