Ouch i hate teachers like that. Luckily i dont have many of those in my school ; D also yeah last summer and he had chopped off his index, middle, ring, and pinkie finger rip. but it didnt seem to hold him back ; D
Also my parents had a friend a long time ago and he was in construction collage and he cut 3 fingers off with a table saw and he put them in a plastic bag with ice and drove to the hospital and tried to grt them to sow them back on but sadly they couldent xD
