My pinky finger on my right hand was squished by a rock and it healed funny years ago. It's a perfectly functional finger but looks a bit gross, so I decided it had to go. One day I numbed it with some pain killers I bought off a guy down the street, then cut off the circulation with an elastic and used an exacto knife to cut down to the bone. I was wandering around my room trying to decide whether my bolt cutters or hacksaw would be the best thing to cut the bone with, when I realized I was a goddamn maniac.
In retrospect my variable-speed dremel would have been the best tool for the job.
