Why? Are you being attacked by a serial killer with a mask?

ifhes not facing u kick him up the butt so he flys across the room into a glass cupboard then chop his hands of and put him in a head lock thats what id do (scary movie)

i would get close to the serial killer and make him think that i was his friend then ask him to take his mask off

Okay, lets see... well, for one if u get close enough u just pull it off - realy boring, haha. Um, you could knock him out, then take it off and take a pic; then u go outside and tie him to a wooden post and cover him and the wooden post in oil and VERY flamable stuff; then u light it up! Watch the mother f*cker BURN!!! Mwahahahaha!!!!

by chopping of its head, somehow
