In Alexander Kuprin's story ‘The Duel’, the regimental commander reprimands the drunken Captain Svetovidov and gives him one more chance, ordering him to prepare the company for the review in a week. "For the last time. But, remember, this is the last time. Do you hear me? Nail it on your red, drunken nose." What should the captain have done?

In the old days, a 'nose' was a name for a special board or tag, on which special marks were put and, thus, marked, for example, debts, days of the week, purchases, etc. In general, everything that needed to be memorized you can "зарубить на носу" (‘zarubyt na nosu’) or ‘nail it on the nose’ . You could say it was an ancient version of a calendar with reminders, a daily planner and even a calculator. You looked at your nose and you remembered right away. 

Often, the plaque was divided in half: one half was kept by the debtor, the other half by the lender. As the debt was repaid, the notches could be cut off. And, for "authorization", the halves were matched, so that the creditor knew that the debt was being settled for that particular debt.
