During Dipper and Mabel's excursions through time in "The Time Traveler's Pig," they accidentally fall into the Mecc's covered wagon during their traversal of the Oregon Trail, where Grady mistakes them as the children of his heavily pregnant wife.
He has a brown mustache, a simple hat, short brown hair, sideburns, and brown clothes.
