I did it in Ireland at a remote fuel store, walking around the nose of the B206, slipped on wet grass, grabbed out at anything to stop myself falling, and ended up grabbing the pitot tube (obviously not on purpose...). End result, was muddy trousers, 3rd degree burns to my hand, and still having to complete the flight as tasked. I decided that quite a few holes in the 'Swiss-Cheese' had lined up that day, and never did it again.
