While the 4th Wiseman was Chuck Norris - who gave Jesus the gift of beard, there was, in fact, a 5th Wiseman. Cloaked in black, identity a secret, he came bearing the gift of ninja - a gift so powerful that the newly bearded Jesus immediately burst into tears upon receiving it and hid the ninjas away from the rest of the world.

And that is why you never see ninjas...until it's too late. *evil laughter*
