Old age is when the liver spots show through your gloves.

In a single punchline, Diller turns a common marker of aging—liver spots—into a visual gag that depends on exaggeration and incongruity. Gloves are conventionally used to conceal blemishes or to appear “put together,” so the idea that age spots would show through them comically suggests aging has become impossible to hide. The joke also satirizes vanity and the social pressure (especially on women in mid‑century American culture, where Diller built her act) to mask signs of age. Like much of Diller’s humor, it uses self-deprecation and bodily detail to deflate pretension while making aging a shared, laughable experience rather than a private embarrassment.
