The day after Christmas: When we all have two more ugly sweaters.

Kilborn’s joke riffs on a familiar post-holiday reality: Christmas gift-giving often produces duplicates of unwanted items, especially novelty clothing like the “ugly sweater.” By defining “the day after Christmas” not by sales or relaxation but by an inventory of regrettable presents, the line satirizes consumer excess and the social obligation to exchange gifts regardless of taste. The humor depends on shared cultural recognition of the ugly-sweater trope and on mild self-mockery—“we all” implicates speaker and audience alike—turning a potentially cynical observation into a communal punchline about holiday aftermath.
