Mind-switcher

The Mind-Switcher is a mind-switching machine which allows two users to switch minds. It is, however, unable to do so when these two people already switched their minds with each other before. Professor Farnsworth and Amy Wong started working on it in 3008 and finalised it in August of 3010.

In "Bender's Game Part 1", the Professor was performing experiments with monkeys, which apparently died. The Mind-Switcher was cleaned up in "The Prisoner of Benda" to be reused by their creators, who wanted to switch bodies. A few days after the cleaning, it had already been tried by Fry, Zoidberg, Sweet Clyde, Bubblegum Tate, the Wash Bucket, Leela, Emperor Nikolai, Bender and Hermes.

It is currently stored at the Planet Express lab.
