That's right, today is the Day of the Ninja. If you're not celebrating, you need to be. ASAP.

You don't know how to celebrate the Day of the Ninja? No worries, we've got everything you might need to know right here:

First things first, you need to come up with a ninja name. Make it awesome.

Secondly, you'll need a costume. If you like to keep things simple, perhaps just a mask for you. But if you're really into holidays and costumes, I'd recommend a more elaborate costume for extra fun.

Thirdly, watch this video and make mental notes of everything it teaches you.

Now, get out there and celebrate the Day of the Ninja like you should.
