Fruity Pebbles Weed
The earliest commercials produced by Post's ad agency D'Arcy Masius Benton & Bowles with cooperation from Hanna-Barbera featured the animated Fred Flintstone and Barney Rubble (as voiced by Alan Reed and Mel Blanc, respectively) interacting cheerfully with live-action children, eating the cereal around a typical household breakfast table; others showed Fred and Barney enjoying the cereal with their wives around their Bedrock breakfast table or in other locales and situations in Bedrock. Commercials after about 1978 were entirely animated, and would have a typical plot repeated with various differences. Fred eats cereal while Barney would want some as well; to that end, Barney would either disguise himself or distract Fred from his bowl of the cereal using various creative and increasingly outrageous means. While Fred was distracted, Barney would eat some Pebbles, but Fred would quickly discover Barney's lies, usually due to Barney's excitement at eating the cereal would cause his costume to be destroyed. Angry about his breakfast being stolen, he would normally exclaim, "Barney! My Pebbles!" Barney would then chuckle and deliver a comedic line while running away from the angry Fred, and Fred would give chase.
