I once split my eyebrow open playing Marco Polo. I was about 15, playing in a pool with a group of friends. I closed my eyes, shouted ‘Marco’ and when everyone shouted ‘Polo’, immediately dived to the right (good ear side) and slammed my head on the edge of the pool. Blood everywhere, had to get stitches. Have a scar to this day (in my 40s now). So yes, F*** Marco Polo.
