Sniped by a 40 year old chain

According to my friend, Italian doctors are hilarious. My friend was sniped by a 40 year old chain while running. I know, she clearly is not Italian as they do not run, nor hop over chains, but none the less she speaks Italian...or at least she did before she was sniped. Keep the story short. She runs, she's sniped, falls on cobbles, screams, no ambulance, taxi to hospital, broken knee cap. I will leave the artistic license up to you on this one, I have confidence in your ability to animate it in a highly dramatic fashion. Now back to the doctors. Was it a moto accident? No, I fell while running. Where? The chain at Ponte Siste bridge. Did you see the chain? Yes. Are you sure that you saw the chain, it has been there for 40 years? Yes, I am sure I saw it. Ok, then we will scan your knee and have you fitted for some new glasses.
