The rules were simple, the plan was deadly. Everyone attending knew it was mandatory to acquire and wear a ninja costume.
Some of my friends went all out and bought the real deal, all the way down to the split toed boots, nunchucks and throwing stars, while some waited to the very last second and wore womens Forever 21 tights and an tank top - with instruction provided by a youtube link on how to make a regular T-shirt into a ninja's mask.
We had a fun pub crawl, no one saw us coming - and no one heard their screams.
And just like that..... we were gone.
