George used the Forgetchamacallit 2000 to retrieve the real Combine-O-Tron 2000 before it got smashed by Trixie. He then used it on Miss Singerbrains before going back to the present with Harold. Later, George used the Forgetchamacallit 2000 to erase the memories of the local news crew.


  • The Forgetchamacallit 2000 is similar to the Neuralyzers in the Men in Black series. Both are small devices that erase memories via flashes.
