Well naturally if we have the International "Talk Like a Pirate Day" then obviously we need the "Annual Day of the Ninja".
December 5th is the Day of the Ninja. Plague your co-workers with ninja-ness and wear a ninja mask to work! Got the day off? Run wild in the streets, or dress like a ninja at the mall! Just show the world that YOU ARE NINJA!
December 5 - Annual Day of the Ninja
Now go flip out and wail on guitars!! Be Awesome!!
