What is a good excuse for a sprained ankle?

So I sprained it pretty darn badly while working at a plastic factory. You see, my family wouldn't accept me knowing that I was osciated with plastic. Plastic is bad, but I needed the job to pay for our compost machine. I need a better excuse to tell my family how I severly injured my ankle. If you answer this well, you will not only get 10 points, but I will also pray to the Whale Gods of your safekeeping. Thanks friends.
