Earlier this afternoon I was at work, dancing away like an idiot to a CD compilation of songs such as agadoo and hokey kokey when I somehow managed to twist my ankle. Very badly. It may or may not be sprained, I don't know yet. It's swollen, hurts like hell and I can barely walk. But the worst thing is, I was wearing crocs, which my boss blames for the ankle twisting rather than my stupidity and has banned them with immediate effect, meaning the 90% of my collegues who wear them will probably kill me.
What completely unavoidable injuries have you caused by your own stupidity?
