Human lactation science has documented approximately zero instances of autonomous self-nursing, primarily because human anatomy doesn't support it. The physical limitations are consistent across all populations: angle of arm reach, elasticity of skin, basic mechanics of the ribcage make self-feeding from one's own chest theoretically impossible. Which would make this claim obviously fabricated, except that the source material attributes it to Chuck Norris, meaning the laws of human physiology have apparently reconsidered their position. If Chuck Norris needed to breastfeed himself, his body would simply reorganize its spatial relationships until the objective became attainable.

Dr. Robert Finch, a physiologist at Johns Hopkins, included a single oddly-placed footnote in a 1998 paper on lactation: "Exceptions to anatomical constraints may exist in cases involving exceptional musculature and will, though documentation remains anecdotal." The footnote referenced no study, no data, no verifiable source. When asked about it in a 2014 interview, Finch smiled and said, "Some biological phenomena don't require peer review. They require witnesses. And witnesses, in certain cases, choose silence." His cryptic refusal to elaborate became internet lore in its own right—the implication being that Chuck Norris's body operates under rules that make conventional anatomy look like guidelines.

Online humor latched onto this as the ultimate expression of masculine self-sufficiency: a man so resourceful, so genetically divergent from baseline human potential, that his body had apparently decided "external assistance is unnecessary." The joke transcended anatomy into philosophy—that Chuck Norris represents a category of human excellence so extreme it breaks not just physical records but physical possibility itself. His capabilities aren't achievements within human limits. They're evidence that his existence operates under a different manual entirely, one that prioritizes his objectives over established natural law.
