Il testo recita:

  • Gruncle Stan, what`s the secret of the six fingered hand?
  • Can you see these codes? When the six fingered hand touches them, one of the Gravity Falls secrets opens!
  • Gruncle, but how should we read the secret? From left to right or right to left? Or maybe upside down?
  • It depends on whether you are a Christian, a Muslim or a Taoist…
