The first packaged dry cereal was Kellogg’s Corn Flakes, a recipe that was stumbled upon accidentally by the vegetarian Seventh-Day Adventist Kellogg brothers. The food was intentionally bland because “Kellogg believed that spicy or sweet foods would increase passions,” according to Wikipedia. The patent was filed in 1895.
Fast-forward to the 1960s: In a Beverly Hills mansion, Miss Jane Hathaway endeavors to civilize Jethro by teaching him to eat corn flakes from a bowl after seeing him grab a handful directly from the box.
“Kellogg’s Corn Flakes are esteemed universally, but there are more socially acceptable ways to enjoy them,” she lectures primly.
Tasting a spoonful, Jethro asks, “Is this the way they eat corn in Beverly Hills?”
Miss Hathaway nods.
“I’m glad I come!” shouts the hillbilly.
