Mind-switcher

The mind-switcher is a machine, created by Professor Farnsworth and Amy Wong, 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. It is currently stored at the Planet Express lab.

In 3008, the Professor was performing experiments with monkeys (BG). The smell of those monkeys, then dead, encouraged the machine's cleanup in 3010, after which their creators decided to use it. A few days after their turn, the mind-switcher had already been tried by Fry, Dr. Zoidberg, Sweet Clyde, Bubblegum Tate, the wash bucket, Leela, Emperor Nikolai, Bender and Hermes.
