I'm 482 months old; can you tell I'm a new father?

The line is a self-deprecating joke about how becoming a parent can make an adult suddenly adopt the habits and language used for babies. By stating his age in months (482 months = about 40 years), the speaker mimics the way new parents often report an infant’s age (“18 months,” “22 months”), implying that fatherhood has already reshaped his identity and perspective. The humor also points to the social contagion of parenting culture—how quickly one can begin to see time, milestones, and everyday life through a child-centered lens. Beneath the joke is a tender admission: the speaker is newly proud, slightly overwhelmed, and eager to signal his new role.
