Everyone knows about the pinky getting cut-off, though it’s considerably more rare now.
Another way to collect is to kidnap the debtor, and put him on a really hellish boat for a year or two.
Another one is to perform a home-invasion, then gag the married couple, tie-up the husband, and then hump his wife and/or his daughter in front of him.
Sorry.
boat = to work on a tuna boat
