How to Piss off Michael Myers:
When he starts walking towards you with his knife, run down the street yelling, "The Tooth fairy's coming! The Tooth fairy's coming!"
Replace his butcher knife with one of those fake plastic ones, and watch as he tries to kill his sister with it.
Call him Michelle when you see him next.
Dye his signature uniform highlighter pink… Suddenly, he seems less threatening…
Hide his mask.
Kill his sister, and then laugh at how he'll never be able to complete his life's goal in his face.
As he tries to kill you, just keep running down the road, and see how long it takes for him to catch up, when he's finally within range to kill you, take off like a bat out of hell again, repeat until you die of exhaustion, or he gives up.
Make him laugh or talk, don't ask me how, just do it. I'm sure he'd be pissed if you made him break his 15 years of silence.
Set his House on fire… With him in it.
