Trivia: If you watch closely, after Fry is leaning on the chair just after the countdown to ten reaches zero and he loses his balance, they cut to a close-up of the chair's legs falling over. You can see Nibbler's shadow cast on the wall in front of him. This was however retroactively added to the first season DVD. In the original airing of the pilot on TV Nibbler's shadow was not present.
Revealing mistake: Near the end of the "Bendee-Boo" segment, while everyone is laughing, one of the Harlem Globetrotters' (between Amy and Leela) right arm keeps disappearing and reappearing several times in one shot.
Other mistake: Bender wears a magnetic bow tie. However in series 1 episode 2 it's shown magnets screw up his circuits and make him sing songs. It's mentioned in a previous entries correction that it's only when the magnet is near his head. This isn't true as it's shown in others episodes that it happens when a magnet is attached anywhere on him.
