Bill Gates was granted a patent Tuesday for inventing 'a software assisted mind amplifier' — aka Guardian Angel — that protects one from sex offenders, the FBI's most wanted, and bad jokes. Not to be outdone, Amazon scored a patent for sending video clips to customers of their order being packaged for shipment.
