My mom breast-fed me. It was only 2 percent.

A typical Wendy Liebman one-liner, the joke hinges on a deliberate misreading of “breast-fed” as if it were a measurable ingredient percentage rather than an all-or-nothing act of infant feeding. By treating breastfeeding like a product label (“only 2 percent”), the line satirizes how people quantify and compare parenting choices, and it also plays on the cultural familiarity of “2%” as a shorthand for low-fat milk. The humor comes from the abrupt pivot from a personal, intimate topic to a banal consumer metric, undercutting sentimentality with deadpan absurdity.
