Can I go to Ninja school? Can I, huh, can I? Can I go to Ninja school?
So far as I know there is no such thing as ninja school, so no.
I would be an awesome ninja. I would ninj on Attila's arse until he didn't know which way was up.
Being a Ninja calls for stern self-discipline, fearlessness and the ability to stay absolutely silent...do you really think you have what is needed?
I stayed quiet when you wore those jeans out in public.
