My best one yet was when i decided to tap 30 oblong ceramic cabinet knobs in my hand..with the 18v drill.. needles to say i got through 29 and on the last one i felt like i didn't thread in deep enough so i went just a bit deeper and BAM! Knob snapped and caught on the tap and i found myself with a ceramic blade spinning at 500 rpm in my hand. 30 stitches later..
10 on the thumb, 10 palm and 10 between the index and middle fingers! taking off the dressing to pull the stitches out.
