7. Basketball - Deadly Friend
Sometimes, the effect of an improvised weapon is to be expected - something heavy is bound to leave a mark, anything sharp is likely to pierce, and inappropriate things are bound to be completely ineffective. That is unless you live in the world of Wes Craven's ludicrous Deadly Friend, the bonkers sci-fi horror that sees the micro-chip of an occasionally autonomous robot implanted into the brain of a dying teenage girl, who then goes on a quest for vengeance, killing both the abusive father who almost killed the girl, and the reclusive neighbour who shot the robot on Halloween. That second murder is the greatest part of the movie, as the robot-minded Samantha (played by Kristy Swanson) destroys the entire head of her victim - played by Mama Fratelli herself Anne Ramsey - with just one throw of a basketball. It's unintentionally hilarious from start to finish, and it's certainly not helped by the very obvious mannequin that replaces Ramsey half-way through the shot. http://youtu.be/lSW2pPlZF-M
