Myself - twice:

(1) explosion of brake fluid in the face directly in the right eyeball - excrutiating pain for hours, left eye totally blind for 3+ days, right eye totally blind for over a week, sensitive to sunlight for almost a year (could not go outside without HEAVY sunglasses) and today this is why I have 'droopy' half-closed eyelids (I got into the habit of carrying them that way);

(2) caught between 2 moving cars and while escaping jumped straight in the air, caught my left foot between the bumpers crushing all 5 toes - on crutches 11+ months, took 2+ years to heal.

Both are very entertaining stories
