Continuity: When the crew and Bender are sitting on the couch, Bender says, " Oh, oh, oh! get ready for this part!" Note the vent behind him is missing the three lights that have always been on it.

Continuity: Bender is shown to be wearing clogs in the scene where he arrives back from Holland after saving a turtle. However, a few seconds later when he's knocked over, the clogs are gone.

Continuity: The lava is close to the machine, until Fry runs to it, then it's a long way away.

Deliberate "mistake": The fossilised dog looks like the dog did when he was young; it should look old and decrepit, as the dog was when he died. (Presumably deliberate, to avoid a spoiler.). Submitted by Moose

Continuity: When Amy and Leela are wrestling, Amy's leotard changes several times. It varies between pink knee-length leggings and no leggings at all.

Continuity: People (even the dogs) flying through the asteroid belt wear space helmets, but on the asteroids themselves, they don't.

Continuity: The rotation of the feeding mechanism on the newspaper gun changes. It first spins counter-clockwise when Hermes starts firing, then it is shown spinning clockwise for the shot where Dwight takes over.

Continuity: The comic books pages become blank when Cubert is ripping off the back page.

Continuity: The back page that has been ripped off is put in the envelope with the top part showing the right way up, but it was folded so if the ads side of the page was showing, either the middle part or the top part upside down would show.

Continuity: Just before Leela unhooks her bra, she drops her singlet on the floor. The singlet she drops is a pale orange colour, matching her bra, but Leela's singlet is white.

Continuity: In one of the first shots at the Freedom Day celebration in front of the Lincoln Memorial, we see a banner, with the text "Freedom Day - Express yourself. I hate my job.", suspended between to poles. Some of the banner can also be seen during the first part of Nixon's speech. But when it gets time to lower "Old Freebie" (the flag) the banner has disappeared and the flag is lowered into the position where the banner hung before. And the banner was tied to the two poles so they can't have raised it.

Continuity: On board the Nimbus where Zapp asks for the activation codes for the global defense network, it immediately after cuts to a shot of Kif Saying "Aye Aye sir". In the background of the shot sit two ship crew members, the brown haired one on the left disappears in the following shot.

Continuity: When Zap Brannigan is about to shoot at the evil holograms the horse has fangs, but when they fly out the window the horse's fangs disappear.

Continuity: Zoidberg wasn't in the machine to begin with, yet he appeared later. When it spins you see the whole inside of the machine - he's definitely not there. Submitted by Piemanmoo

Continuity: When Leela is found on the door step she has a bracelet on her wrist but in the next shot it is gone.

Continuity: When the door is closed on the "ageing chamber," notice that the side the hinges are on changes between the external and internal shots.

Continuity: When Fry first takes the tangled Christmas lights out of the fake box, they are all red and blue. However, when the shot cuts outward to get a wider view, many of the lights have turned green.

Continuity: When Leela looks in the box, the wall behind her is red, then blue when it cuts back, then red again, and finally blue as she enters the other universe.

Continuity: Just as Hermes A is about to shoot the box into the sun, all the crew (A and B) shoot out into the airlock. However, Hermes B doesn't come out of the box and just appears in the pile. This is confirmed in the commentary. Submitted by SexyIrishLeprechaun

Continuity: In the very beginning scene, where Fry and Leela are talking, there is an explosion. When some ceiling falls down there is one big bit and three small bits next to Leela's foot but then a few seconds later there is one big bit and a few small bits all in different places.
