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.
Suggested correction: This has proven to be in the original airing.
