Is This Tropable?? Alternate Title: Magical Old Folks (to go with Magical Negro, Magical Queer, Magical Native American etc) When a supernatural terror plagues the neighbourhood, nobody has any idea what's going on... except for that one Rambling Old Man who's always telling fanciful stories. Apparently when they talk about the "wisdom of the ancients", they're not talking about the precursors -- any old senior citizen will do. Subtrope of Older and Wiser, related to Ancient Keeper.
- The Mechanic in South Park who tends to show up out of the blue purely to do this, and then disappears.
- Grampa Joe in Bad Machinery, who tells the kids about Selkies and Wereseals.
- Grandpa Simpson has played this role a few times (generally in Treehouse Of Horror stories), and subverted it in others.
Hello, Unknown Troper. You'll need to get known to lend a hand here.
