History Recap / FuturamaS4E15TheFarnsworthParabox

-->'''Farnsworth-1:''' (As Farnsworth-A shakes his head) Now, now, perfectly symmetrical violence never solved anything.
* ForWantOfANail: Spoofed when the drastic differences between universes are said to be based on the outcomes of coin tosses, even though unrelated things like hair color and the color of the sky are still different. Among other things, Bender is gold instead of grey, the parallel Professor has a major head wound from attempting to remove his own brain, and most major of all, Parallel Fry and Leela are married.

-->'''Amy-1:''' Is that pink nail polish?\\
'''Amy-A:''' Is that not-pink nail polish?\\
'''Amy-1:''' The Professor was right, you are evil! And shallow!\\

-->'''Narrator''': [[MeanwhileBackAtThe Meanwhile, in Universe A]], Hermes-A heads towards the Sun... -A.

-->'''Farnsworth''': Oh Lordy Lou, help! Buddha, Zeus, God! One of you guys, do something! HELP! Satan! You owe me!

-->'''Eyeless Hermes:''' We didn't see anything... EVER.

-->'''Farnsworth''': This box contains ''our own universe!!!''

-->'''Narrator''': Meanwhile, in Universe A, Hermes A heads towards the Sun. ''[{{beat}}]'' A.

* OhCrap: The Professors, when they stop Hermes-1 from destroying Box-A, and realize this means if ''that'' Hermes was going to do it, then Hermes-A, who's unattended and doesn't know what's going on, is probably about to do the same thing.

-->'''Bender:''' Yeah, Leprechaun Universe is fine... if you haven't seen ''Pirate Universe!''

-->'''Leela-1''': Hermes, aren't you curious about the fact that there's two of everybody?
-->'''Hermes-1''': [[LittleNo No]].

* BiggerOnTheInside: When Leela first peers inside the box, she remarks that it's "deep... deeper than a small box should be". She then falls into it, and we learn the trope has been taken UpToEleven: the box contains an ''entire parallel universe'' despite being roughly the size of a shoebox.

* PlanetOfHats: Taken UpToEleven; every other alternate universe after Universes 1 and A is defined by a single characteristic.

-->'''Narrator''': Meanwhile, in Universe A...

-->'''Alternate Farnsworth:''' (As the original Farnsworth shakes his head) Now, now, perfectly symmetrical violence never solved anything.

--->'''Alternate Farnsworth:''' (As the original Farnsworth shakes his head) Now, now, perfectly symmetrical violence never solved anything.

* DoomyDoomsOfDoom: The parallel Benders do a nifty reverb-double-[[https://www.youtube.com/watch?v=_49iNqxOnH4 DOOOOOOOOOOOOOOOOOM]]!

* AllWomenAreLustful: When Farnsworth sticks his head into a universe populated by only women[[note]] Whether it's [[LadyLand completely women]] or it's just women in the immediate vicinity of the box isn't explained[[/note]] he pulls it back out covered in multiple kiss marks. Apparently finding this strange withered old man whose head juts out of a box in the middle of the room irresistible.

-->'''Hermes:''' We didn't see anything... EVER.

* ForWantOfANail: Spoofed when the drastic differences between universes are said to be based on the outcomes of coin tosses, even though unrelated things like hair color and the color of the sky are still different. Among other things, Bender is gold instead of grey, the parallel professor has a major head wound from attempting to remove his own brain, and most major of all, Parallel Fry and Leela are married.

* {{Jerkass}}: The Bobble-headed inhabitants of Universe 1729.

* MikeNelsonDestroyerOfWorlds: Hermes almost ends up unwittingly destroying Universe 1 by throwing Box-1 into the sun, and is moments away from doing so before the gang warns him not to.
* MindScrew: This episode is all over this, starting with the creation of a box that contains a parallel universe (while simultaneously, the parallel universe creates a box containing the other parallel universe) and ending with the two Farnsworths somehow pulling each other's boxes through each other so that both universes [[RecursiveReality now contain a box containing their own universe]] (and the boxes themselves are probably worth something as well).

* NeverMyFault: While the Zoidbergs are complaining about their mistreatment, we hear some of them complains are things like "put on pants, Zoidberg!" and "stop spraying me with ink, Zoidberg!"
* OhCrap: The Professors, when they stop Hermes-1 from destroying Box-A, and realize this means if ''that'' Hermes was going to do it, then Hermes-A, who's unattended, is probably about to do the same thing.

* OtherMeAnnoysMe: Pretty much everyone is irritated by their alternate counterpart at first, except for [[{{Narcissist}} Bender]] who gets along swimmingly with his doppelganger.

* RecursiveReality: At the end, the Professors from both universes grab the other universe's box and end up with boxes containing their own universe.

* TemptingFate: The Professors hid Box-A in Professor-1's coelacanth tank, reasoning that only a "crazy lobster" would look in it. The Zoidbergs have by that point already stolen the box.

* UnusuallyUninterestingSight: Lampshaded when Hermes-1 walks in and starts chiding everyone for not destroying Box-1 yet:

* HighTimesFuture: It's shown that many alternate universes exist, and one of them is a PlanetOfHats for stoners. It's named Universe 420.
