    Trivia, Notes, Quotes and Allusions


    • TRIVIA (3)

      • When Roy is having a seizure, Sam puts a wooden spoon in Roy's mouth "to keep him from swallowing his tongue". This phenomenon is a myth. It is physically impossible to swallow one's tongue.

        When someone is having a seizure, you should roll them on their side so that their tongue doesn't block their airway; never put something in a seizing person's mouth. As a doctor, Sam should know this.

      • In several scenes in this episode, Sam and Al are outside. In these scenes, you can clearly see Al's breath due to the cold weather. As he is a hologram, this should be impossible.

      • For some unknown reason, Al is wearing gloves this entire episode.

        (This is most likely because most of the episode takes place outside and Dean Stockwell was keeping his hands warm.)

    • QUOTES (1)

      • Daniel: (referring to Bigfoot) You think he might be here?
        Roy: There's no way to tell. He could be a thousand miles away or he could be watching us right now.
        Al: I hope that hairy devil can't see holograms.

    • NOTES (3)

      • This episode is written by John D'Aquino, who appeared as Frank LaMotta in the Season Two episode "Jimmy" and Season Five episode "Deliver Us from Evil."

      • This is one of the several episodes from the series that proves, to the characters, the factuality of urban legends and supernatural phenomena. Other episodes include:
        "A Portrait for Troian" (ghosts) from Season Two, as well as
        "Temptation Eyes" (psychics),
        "Ghost Ship" (The Bermuda Triangle),
        "It's a Wonderful Leap" (angels) and
        "The Curse of Ptah-hotep" (mummies) from Season Four, and
        "Star Light, Star Bright" (UFO's) and
        "Blood Moon" (vampires) from Season Five.

      • With "Oh boy" usually being spoken by Sam after he leaps, this episode sees Al say it right before Sam leaps as they both spot Bigfoot in the distance.

    • ALLUSIONS (1)

      • Luke: No, and I didn't see the Loch Ness Monster or little green space men either.
        The Loch Ness Monster is an alleged dinosaur-like creature that is fabled to live in the Loch Ness (Ness Lake) in Scotland. Like Bigfoot, Nessie the monster exists in urban legend and has only been substantiated by questionable photographs and vague stories of sightings.
