The Continuum Transfunctioner is the MacGuffin item in the comedy movie Dude, Where's My Car? released by 20th Century Fox in 2000.
It is a very mysterious and powerful device, reputedly capable of destroying the universe. Described as a device whose "mystery is exceeded only by its power", it initially appears as a Rubik's Cube.
"Solving" the Rubik's Cube will activate the Transfunctioner; its "keepers" (aliens described by the film's main characters as "Totally gay Nordic Dudes") used its power upon activation to banish a 50-foot-tall alien to Hoboken, New Jersey.
It is also an item in the MMORPG Kingdom of Loathing.
