Foolish Earthlings is an intergalactic reality show produced by Kang and Kodos. Episodes are created by secretly recording humans' entertaining behaviour using wasp cameras hidden throughout Springfield.
When the show's ratings began to drop, Kang and Kodos introduced a new form of Buzz Cola to Springfield designed to make the citizens behave more erratically. When this failed to boost ratings they introduced the cola into the water supply and began selling laser guns so everyone would go insane and start shooting each other. Even though this plan was thwarted by Bart, the cola eventually started causing zombies to raise from the dead. However shortly after this, Homer discovered the aliens' weakness was nuclear waste and used this to kill them both. Homer's defeat of the aliens caused Foolish Earthlings' ratings to soar and he became immensely popular among Rigellians overnight.
