yeah, like that is totally realistic.

Lumberjacks have waaaaay more experience with combat than with wood. they gotta drive off the opposing lumberjacks and all the ca-razy wild jaguars and such. =D

little did you know, but there is quite a rift between the lumberjacks. there's a war going on.

besides, all they have to do is cut down a tree and have it fall on the unknowing ninja. they could rig all teh trees in teh forest to just fall on the poor fewls
