Bugs Bunny is the most famous character in the Warner Brothers stable of animated characters. Although formative versions of the character dated to 1938, the fully realized Bugs Bunny is generally recognized as having made his debut in the 1940 Academy Award nominated short subject A Wild Hare.
Bugs, along with Daffy Duck, appeared with the Muppet Babies in the 1990 animated television special Cartoon All-Stars to the Rescue. Bugs also appeared in the pro-recycling short "Yakkety Yak- Take It Back," which appeared on Sesame Street in the 1990s.
Bugs had been referenced on Sesame Street years earlier. In an Ernie and Bert sketch from 1982, Ernie is desperately seeking Dr. Livingstone, so as to ask him one vital question: "What's up, Doc?"
