Episode Two: The Series Has Landed - S1-E2
Other mistake: When the Moon Patrol officers throw Bender out of the airlock onto the moon's surface, they are exposed to hard vacuum, but they aren't wearing space suits. Throughout the episode it is established that the moon's "atmosphere" is a vacuum and protective suits are necessary - when the farmer removes his helmet he begins to asphyxiate instantly.
Other mistake: A few of the liquid people are shown wearing clothes; while you can usually see through the people to the walls, etc, behind them, you can't see the clothing through them. (00:11:10)
I, Roommate - S1-E3
Other mistake: When the crew are leaving Fry's new apartment, Amy slips on the banana skin again and falls over, and for some reason Fry tries to shut the door without her leaving. Maybe it was easier than drawing her getting up, but still worth a look. (00:15:30)
Other mistake: When the robots are building a Tetris wall, there is a section on the left made up of two red 'L' bricks. However, the upright L block is not the same as the other red blocks, because it is flipped laterally. (00:09:05)
A Big Piece of Garbage - S1-E8
Other mistake: When Professor Farnsworth was presenting the crude drawing of the Smelloscope to his scientific peers, he wiped the napkin which it was drawn on on his forehead, causing all the ink to smudge. But why isn't there any ink on Professor Farnsworth's head? (00:05:30)
Answer: The initial number is 0101100101 = 357. When reflected in a mirror, however, it reads 1010011010 = 666 (the number of the Beast). It is a parody of The Shining, where the words Red Rum are seen as the word murder in the mirror.
