its easy. go to the nearest out door hockey rink accompanied with a drill and most likely a philips bit, but bring along some robertsons as well. wait for it to darken outside. next you place the bit into the screw head and grip the "triger" on the drill and remove the screw, repeat on each other screw. there you have it, for free.
well i actualy dont sugest doing this because its moraly wrong and i in no way encourage you to do this.
