How to piss off Kakuzu
Steal all off his thread(the ones he stitches him self up with).
Put them in Tobi's room.
Tell him Tobi stole them
Laugh till you faint from lack of air while Tobi runs around from Kakuzu trying to kill him
Brake Hidan's shower
Tell him to shower in Kakuzu's room
Before the 6th one give Kakuzu laxadives
Then laugh when they see each, one naked and one taking a poo
When he's trying to stitch himself up yell as loud as you can and make him mess up
Tell him that the Asylum as room for him now(If you value your life don't do this one)
