1980’s schlock horror Friday The 13th introduced the world to the undead machete-wielding serial killer Jason Voorhees. The mummy’s boy murderer terrorized the teenagers at the Crystal Camp Lake summer camp for years. And now he’s back. Well, sort of… The prankster in this terrifying video reenacts the brilliantly creepy scene where Jason emerges from the lake in his hockey mask (amongst others). No one’s expecting his appearance, so it makes for a Helluva scary practical joke!
