Sonny the Cuckoo Bird - "I'm Cuckoo for Cocoa Puffs!, Cuckoo for Cocoa Puffs!" was the uncontrollable scream of Sonny the Cuckoo Bird on the animated General Mills cereal commercials begun in the 1960s. Sonny, who wore a vertically-stripped turtleneck sweater, co-starred with a Gramps, an elderly bird character who tormented Sonny with the sight of Cocoa Puff cereal. When the bearded Gramps was fazed out, Sonny interacted with live child actors. The Sonny the Cuckoo Bird campaign was created by the Dance, Fitzgerald and Sample Agency. TRIVIA NOTE: The book "Sex, Drugs, and Cocoa Puffs: A Low Culture Manifesto" by Chuck Klosterman (Scribner; ISBN: 0743236009) is an intelligent look at the "trivial" subjects that shape our lives.
