Are You a Ninja?

Came across this on 6Eight, clever, though I'm niggled by a slight concern that it falls foul of de-Christian doctrine no.3 (see Tuesday mornings post). Part of the ninja mission is to recruit and train more ninjas, and to introduce them to the supreme ninja. Having said that, this looks like its aimed at people outside the church, so it doesn't have to tick every doctrinal box that picky evangelicals like me want to wedge it into.
