Christmas is a time when everybody wants his past forgotten and his present remembered.

Phyllis Diller popularized this line as part of her holiday-themed comedy material, in which she often skewered domestic ideals and social rituals. In the postwar era when Diller rose to fame, Christmas was increasingly commercialized and socially performative—an occasion for family gatherings, gift-giving, and public displays of cheer. Diller’s persona (the frazzled, self-deprecating suburban wife) made her especially apt to joke about the pressures of being judged by relatives and neighbors. The quip plays on the season’s emphasis on goodwill and reunion, suggesting that people use Christmas as a kind of social reset: old missteps are politely ignored while current efforts and generosity are noticed.

The joke hinges on a reversal of what “should” matter at Christmas. Instead of repentance, reflection, or tradition, Diller suggests many people want selective memory: let bygones (embarrassments, conflicts, failures) be erased, while today’s image is spotlighted. “Past forgotten” implies a desire for absolution without accountability; “present remembered” points to craving recognition—being seen as kind, successful, or improved right now. The humor is cynical but observant: holidays intensify social comparison and family narratives, so people become especially invested in controlling how they are perceived. Diller’s line compresses that social psychology into a neat, quotable paradox.
