Dark matter pellets are handled casually, yet when initially introduced in the series they were particularly heavy.
At the Mombil mine, the front panels on the killbots keep changing color, randomly, between shots - green, black, yellow and orange.
At the Mombil mine, after the ship is shot down, the damage on the camera view in Mom's office afterwards is far more extensive than the damage to the ship right after it crashed.
At Cornwood castle, there are four gnomes and seven dwarves at the dance. When the lead breaks his ankle and begs for his life, there are suddenly four dwarves and two gnomes.
After the demolition derby Leela's pony tail is burned off. In the next shot it is back to normal.
The mailbox of Leela's parents house in the sewer reads "Turanga". Turanga may be Leela's 'first' name, but Turanga is actually the family name - Turanga Leela and her parents Turanga Morris and Turanga Munda.
When Mom's three sons are first charging Leela, Fry, and Bender, they are each carrying a lance. But after Bender launches himself with his own lance, their lances seem to disappear; however close inspection reveals that the lance guards are visible and the lances themselves are therefore present but out of shot.
In Bender's Game, dark matter is all done in the form of round pellets, and all of it is mined from Alaska (Mombil has a monopoly on it). In a previous episode _"Futurama" The Birdbot of Ice-Catraz (2001)_, there is liquid dark matter from Columbia. However, all the dark matter is in the form of round pellets (considering where it came from), so it would make a lot of sense if Columbia was the place the dark matter pellets went to be liquefied, not where it was mined.
Cubert Farnsworth and Dwight Conrad are seen playing Dungeons and Dragons using a dodecahedron (12-sided dice). The dodecahedron is used only for damage done by greataxes and barbarian hit dice. It's been claimed that the correct dice used should have been an icosahedron (20-sided dice), ultimately the rules are dictated by the Dungeon Master (in this case, Dwight).
While playing Dungeons and Dragons, after one of the players rolls a 20, Qubert announces he does 2x damage with his pole-arm to a Gelatinous Cube. Whilst in Dungeons and Dragons, Gelatinous Cubes are often immune to critical damage, ultimately the rules are dictated by the Dungeon Master (in this case, Dwight).
The band in Titanius Anglesmith's castle has four gnomes but only a single piccolo is heard.
Fry and Leela are the only ones who seem to know that they are in an alternate universe, with no particular reason. But when they get back to the real universe, they all seem to know what happened.
When Hermes is commanding his army of centaurs with bows drawn, he shouts "Fire!".
The word refers to 'firing' the gunpowder in a musket. Bows on the other hand do not get fired, as that would mean to light the wood on fire.
The word used by archers was and is "loose", meaning to let the arrow loose.
When Hermes is commanding his army of centaurs with bows drawn, he shouts "Fire!". The word makes no sense in this context as he isn't asking them to burn anything. The verb the writers were looking for is "Loose", referring to the arrows being set loose.
