lol it take time for u to realize your in a Genjutsu also by the time u tear off your right ear which u might need to pull out a tool to do so, if u didn't it would only take longer for u to tear off your ear and by time time u reach into your pockent and pull something out and cut your ear which i still think is a stab which wouldn't release u from the Genjutsu if u had read my jutsu..Also by the time u did that I have performing a single hand sign explode the whole area which u standing on also your surround so you wouldn't have time to release yourself and block the explode because it's instantly.
