      When Skinner is going through Mulder's files, you can clearly see a file labeled "Foo Fighters" near the back of the cabinet he is searching. The term refers to unexplained flying objects observed by pilots during World War II and also to the rock band, which contributed a song to the X-Files "Fight the Future" soundtrack.

    • Movie Reference: The Birds

      The schoolyard scene with the bees attacking the children and their teacher is a reference to the Alfred Hitchcock film which contains a similar scene only involving birds.
