Ninjas on the lawn

Along with paranoia, ninjas-on-the-lawn is the most common side effect of cocaine.

asshole: "What is that outside?"

you: "I'm not sure, but i think it could be NINJAS."

asshole: "There are no ninjas on the lawn."

you: "OF COURSE THAT'S WHAT THEY WANT YOU TO THINK; THEY'RE NINJAS."

ninja rowson

Ninja Rowson is one of the best maths teachers to have. He will perform a dance called the Ninja dance where he moves around as If he was a ninja whilst impersonating a Chinese/Japanese accent. He is a good teacher although sometimes he gets in a strop and sits back down in his chair for around 10 minutes of the 60 minute lesson you have with him .
