90's Ninja 

A 90's ninja is somebody that grew up in the 90's and is yet to leave their outdated trends behind them. Wardrobes may include sneakers that flash, orange headbands, and temporary spice girl tattoos.

Guy 1: "I think Fresh Prince is some of Will Smith's finest work."

Guy 2: "Dude, if you would take the N'sync out of your ears for one second you would realize all of the movies he has done since then. You are such 90's ninja."

Schrodinger's ninja 

A person who is not wearing a mask, but still somehow manages to sneak into a place where masks are required, especially when there are guards at the entrance.

I was so confused! This man must have been a ninja to have been able to so easily sneak in without a mask. But if he actually was a ninja, then he would have been wearing a mask anyways! What manner of strange creature was this who was both a ninja and not? It was Schrodinger's ninja!

When confronted by ninja(s), the individual ninja will be far more powerful than a group of ninjas. To see the effectiveness of a group of ninjas simply use the equation power= 1/n, where n is the number of ninjas

Don't worry about the group of 1,000 ninjas, worry about the single guy, according to The Law of Inverse Ninja Strength
