Hilbert's Hotel
Sam kicks a tin-can down the dusty road, wearing Dean's hand-me-downs and shoes that are a size too big. "Infinity plus one."
Dean rolls his eyes and gets a better grip on the duffle bag of knives and guns. Shit's heavy. "Infinity plus two."
Sam stops and smiles, brilliantly, gives the can a vicious kick. "Infinity plus infinity."
Dean just shrugs and reaches out, shaking Sam by the neck until he squirms away. The can's in the ditch, so he starts kicking a rock.
Sam keeps darting glances at him until Dean gives and says, "Infinity plus infinity plus one."
