[HobbitNinj]

actually, a human running on all fours is not anywhere a cool as when stranger does it. watch any little kid pretending to be a dog. they either are on their hands and knees( rug burns and lack of speed) or hands and feet ( in which they move simular to chimps). Either way it is not a good idea... it looks stupid. Too bad we can't run like stranger. that would be a lot cooler.
