In a special Friday the 13th episode, Mack and Olivia uncover some origins of this unlucky holiday, including one man willing to push his luck with superstition, and tales of Norse gods and a dinner party gone wrong which may have brought about the curse of the number 13.
Other than foul language, no real warnings for this one, but you might want to knock on wood after listening. Also slight disrespect of the illiuminati.
