Bugs Bunny that another proposed name for the character was "Happy Rabbit." In the actual cartoons and publicity, however, the name "Happy" only seems to have been used in reference to Bugs Hardaway. In "Hare-um Scare-um", a newspaper headline reads, "Happy Hardaway." Animation historian David Gerstein disputes that "Happy Rabbit" was ever used as an official name, believing that the only usage of the term was from Mel Blanc himself in humorous and fanciful tales he told about the character's development in the 1970s and 1980s; the name "Bugs Bunny" was used as early as August 1939, in the Motion Picture Herald,
Bugs Bunny in both the 855th Bomb Squadron of the 491st Bombardment Group (Heavy) and later in the 786th BS of the 466th BG(H), both being part of the 8th Air Force operating out of England. In 1944, Bugs Bunny made a cameo appearance in "Jasper Goes Hunting", a Puppetoons film produced by rival studio Paramount Pictures. In this cameo (animated by McKimson, with Blanc providing the usual voice), Bugs (after being threatened at gunpoint) pops out of a rabbit hole, saying his usual catchphrase; after hearing the orchestra play the wrong theme song, he realizes "Hey, I'm in the wrong picture!"
