Santiago: Trap door!Joni: Whee!Santiago: Whee?
- In 3rd Grade, taking one of the halves of the key needed to enter the lost city reveals a trap door which leads them back to the fork in the road where they started. This leads to this exchange.

- In ClueFinders 4th Grade Adventures, the villain, Alistair Loveless, needs a Ring of Power MacGuffin for his evil plans:
Loveless: Once I have the ring, I can proceed with... the ceremony!
Professor Botch: Oh, are you getting married? How lovely!
Loveless: I'm not getting married, you twit! I am an evil man, and I am up to no good!
