This One Little Mistake Pippin Made in Lord of the Rings Helped Save Middle Earth

We all know that Pippin (Billy Boyd) can be a handful in The Lord of the Rings. He has a deathly mix of curiosity, clumsiness, and poor judgment that often puts the Fellowship of the Ring in trouble, like that time when he awakens all of Moria. Or that time he reveals Frodo's (Elijah Wood) identity in Bree. Or that time in Minas Tirith when he pledges his services to Denethor (John Noble). There are too many to count, but one of his mistakes ends up being really helpful, especially for Frodo and Sam (Sean Astin) as they infiltrate Mordor. Yes, we're talking about when he uses the Palantír in The Return of the King.
