When I was around 8, a neighborhood kid was swinging around a light pole, just a plain metal pole but it had the wirenut box attached to the side about a foot from the ground, which he was standing on while spinning.

His foot slipped, the corner of this box ripped his ankle open, cut right up from the top of the shoe about 6 inches into his lower calf/ankle.

He screamed and ran home, blood pouring everywhere. Saw him a few days later with massive stitches and bruising all over his leg. Wasn’t as bad as it looked, but fuck me it still makes me wince thinking of my ankle being sliced by a dull metal corner by weight and gravity alone.
