Continuity mistake: When Bender is watching television with Fry, in the background you can see the dart in the background is on the top half of the board in the wall, but when the shot changes it is in the bottom half of the wall.
As the power builds up in Bender, his left eye pops out, making him a cyclops, subsequently being eaten by the Cyclops eater. After the monster dies, Bender comes out, and has two eyes in the long shot, but puts his left eye back in the close up.
