Fics like A Case of Mistaken Identity

After using a time traveler's device to manipulate their future, Dipper and Mabel become trapped in a wintry Gravity Falls more than thirty years ago. There (or rather, then) they find themselves face-to-face with their Grunkle Stan. That's who it is, right? Who else would it be? (Time Traveler's Pig AU)
