Rather than waste paper like a traditional calendar, the Napkin Calendar 2009 by Stas Aki provides extra practical functionality as a napkin.
Printed on napkins that can be used in a regular napkin dispenser, the calendar allows you to vent your frustration at the end of the day by blowing your nose at the day.
I am not sure the calendar will actually last till the end of the year though. If you get the flu, you can run through the calendar in a few days!
