Bugs gives both his and Daffy's birthdays as July 27th and April 17th, respectively. Daffy's first appearance in a cartoon was in "Porky's Duck Hunt" which premiered on April 17th, 1937 and, while a white rabbit had appeared in earlier cartoons, Warner Bros. considers "A Wild Hare", which premiered July 27th, 1940 with a gray rabbit, to be Bugs' debut role and so mark it as his birthday.
