Scooby, "Scooby Doo"

Fred Silverman, the head of children's programming at CBS, said that the Great Dane's name, Scoobert Dooby "Scooby-Doo" Rogers, originated from the "doo-be-doo-be-doo" scatting by Frank Sinatra in the song "Strangers in the Night." Scooby's garbled speech was voiced by actor Don Messick. Everyone talks about the "ruh roh," but no one mentions that he also has opposable thumbs, a prehensile tail and just one pad on the sole of each of his feet.
