Parenting is the most important job on the planet next to keeping Gary Busey off the nation’s highways.

Miller’s line is a characteristic blend of earnest sentiment and abrasive pop-culture punchline. The first clause elevates parenting as a society’s highest-stakes responsibility; the second clause undercuts the solemnity with an absurd, celebrity-specific comparison. Invoking actor Gary Busey—long associated in the public imagination with volatility and reckless behavior—turns “public safety” into a comic yardstick, implying that raising children well matters as much as preventing obvious, immediate danger. The joke also satirizes how modern culture measures importance: even profound duties are framed through media personalities and sensational images. The result is both a tribute to parenting and a critique of our attention economy.
