I mean if you saw one of your teachers as an zombie thats been a bitch to you thats like sweet revenge. What kind of punishment would you do to your teacher zombie.. i would chop her head off then blow it up with ma twelve gage.. and let her blood splatter..lol
Lure her into a class room and then rush out, shutting the door behind you. Some people are so miserable that it's sweet revenge just to leave them be...
Id have to agree with Ben... As much fun as sweet revenge would be, it wouldnt be on your teacher. Itd be on something that resembles a person who at one point may or may not have been your teacher. Screw wasting ammo, Just kill em.
They're kinda human but...
This will be fucked up but grab her head and slam it into the chalkboard. With blood splattered, write your name with her head to finish your last detention
