The Return of the Beast: Part 2 - S1-E2
Factual error: When Betty's humvee breaks down in the middle of the desert, she gets out and steps over a scorpion. The scorpion is shown to have 10 legs (4 standard legs and 2 pincers). Scorpions have 8 legs.
Suggested correction: A scorpion's pedipalps (their pincers) are not legs. Scorpions and other arachnids have 8 legs and 2 pedipalps.
