Knock Knock the Woodpecker

Knock Knock the Woodpecker (performed by John Lovelady from 1981 to 1983 and Noel MacNeal from 1981 to 1986) is a prissy pink bird who lives in the hollow of a tree and tells a lot of knock-knock jokes. She, alongside Goriddle Gorilla, occasionally introduces Gary Gnu whenever "The Gary Gnu Show" segment comes on. Knock Knock also intros the "Book Of The Week In Review" segments by saying "And here's Gary Gnu with the Book Of The Week In Review", usually waking Gary from a nap. Knock Knock uses her sense of humor at times to give Goriddle a taste of his own medicine.
