About a year ago I was pulling my KABAR knife out of its sheath without really looking (don't exactly know WHAT I was thinking) and sliced about halfway into my left thumb, with the whole 8 inch blade starting with the rip teeth to the tip. My actual reaction was "Oh, wow" and needless to say my thumb turned into a faucet. It's not the most rugged-looking scar, but after 9 stitches and a year later it's still a little fuzzy. My friends and I joked about for months and still occasionally do. So, what plans or genius maneuvers (like mine) have you all come up with that horribly backfired?
