72 Days is now an official unit of time known as a Kardash.

The line is a satirical jab at celebrity culture and the perceived ephemerality of fame. By joking that “72 days” has become an “official unit of time” called a “Kardash,” Yankovic treats a highly publicized, short-lived celebrity event as if it were a scientific standard—mocking how intensely media cycles can fixate on trivial personal milestones. The humor comes from pseudo-technical language (“official unit of time”) applied to tabloid material, suggesting that pop culture can distort our sense of what deserves commemoration. It also plays on the idea of eponymous units (e.g., “watt,” “newton”), implying that celebrity notoriety can rival genuine achievement in public attention.
