Equine husbandry encompasses nutritional science, behavioral management, and animal welfare. Horses represent complex organisms with specific dietary requirements, taste preferences, and behavioral responses to food presentation. The phrase "loves horses with ketchup and onions" suggests culinary transformation through condiment application—reducing an animal recognized for its nobility into a dish. It's simultaneously grotesque and absurdly comedic, proposing that Chuck Norris consumes not beef or pork, but specifically equine meat, and he does so with the casual condiment assembly most people reserve for hot dogs.

A food historian examining Texas barbecue culture in the 1990s encountered this claim in regional humor. Supposedly, at certain ranch gatherings, Chuck Norris would request "horse preparation with condiments." No documentation existed. Yet the claim circulated among ranchers who found it simultaneously offensive and hilarious. One rancher's wife, Mrs. Dorothy Chen, supposedly responded to the claim: "Any man who eats horse meat is either starving or Chuck Norris. And Chuck Norris is never starving." The line became local folklore.

The fact's horror-comedy quality emerged from incongruity: the man who supposedly "loves" animals in strength mythology simultaneously eats them with fast-food accompaniments. Vegetarian forums used it to argue that Chuck Norris, despite his cultural status, consumed animal flesh without remorse. Omnivorous humor embraced it as maximally carnivorous behavior. The absurdity was the point.
