Futurama

In an attempt to return to Universe A, the professors created a variety of other boxes. If they all lead to other universes, then the other universes possess a Parabox containing Universe 1. Which still puts Universe 1 in danger, should anyone shake it or destroy it.

Before Leela fell into the box, the walls of the Planet Express building changed from red to blue and back to red. After Leela fell into the box the walls changed back to blue but after the commercial break the walls are red again.

The boxes are shown to contain full universes, but when people jump or look inside, they immediately emerge from the alternate universe's own "parabox" without travelling the enormous distances depicted.

How did the Hippy-Universe Farnsworth manage to build that one Parabox?

In the episode I Dated a Robot (when Fry is doing everything he's ever wanted to do) Farnsworth says there are only two parallel universes - theirs and the one where everyone is a cowboy. However, Farnsworth and his alternate-universe-in-a-box counterpart have now created countless (or at least 1729) parallel universes that didn't actually existed before.

In the scene with everyone sitting around the table (Universe 1 on the left and Universe A on the right) looking at the hologram. Leela 1 is missing her wrist device which is suppose to be on her right wrist but when you see her protesting about being called Universe B the wrist device reappears.

How could the box that fell on Zoidberg A, when he backed into the shelf filled with boxes, fit over him AND the box in his claws) if both boxes were the same size.

When the crew got back to universe A to prevent Hermes from destroying the box, they all jump in the box head first, except Farnsworth who drops the box and goes in feet first. When they arrive in universe A, they all come out head first.

When the crew was picking names for the Universes Leela A suggested Universe A and B, but the alternate Leela said that their Universe would be called Universe 1. Later on Farnsworth A still calls the alternate Professor, Professor B.

Not only is the squishy toy from the "Swedish novelty shop" on Leela's bedside table in the hospital, but on the wall is a landscape picture of a frozen ice planet, similar (the same) to the one in Leela's coma. Hermes also mentions the ice planet.

If you notice very carefully near Fry's coffin, you'll see Fry's fossilized dog, Seymour.

In Leela's coma-dream, Bees are responsible for killing six of the seven main characters - first Fry, then later on everybody else. Leela is the only main character who doesn't die.

When Leela had the spoon with Fry on it, LOOK CLOSELY. The picture of Fry is the same one from the episode My Three Suns.

In Leela's coma-dream, right after Fry's funeral, Leela is on her bed. She tears a piece of paper in half and puts it on her night-table. The camera zooms in, then out; and the paper is gone. Where did it go?

All of the errors between Leela getting stung and awakening in the hospital can be explained. Leela was delusional during her coma. Plus, since she was grieving Fry's death, she wouldn't have noticed the mistakes of her memory.

In Mars University, Guenter's hat was crushed, making him have moderate intelligence while wearing it, and he keeps it that way. Yet, in this episode, Guenter's hat is fine.

RESPONSE: Perhaps this is an untold story. A lot could have happened with Guenter in the 3 years since he last appeared.

Leela got a squez-e cyclops in her coma but when she wakes up into the real state it is on the tabletop besides Leela's hospital bed.

At Fry's funeral, we are shown all of the women Fry slept with at some point in the series (including 'that radiator woman from the radiator planet'), and one of them was his date from S02E10: Put your head on my shoulder. In that episode, she left before their date was over, so he never actually slept with her (he wasn't on his own body anyway!)

Black Boxes also usually have some form of armoring to protect them from impact. Also, this seems to be only a circa 1980s tape recorder. Wouldn't they have more likely moved on to digital recorders?

RE: The same can be said of a lot of the technology used in the show (i.e. Dot-Matrix Printers)
