History
The character may be loosely based on Ol' Rip the Horned Toad.[3]
The frog's earliest name was "Enrico", as given in The Bugs Bunny Show (1960).[4] The character's later, enduring name comes from the song "The Michigan Rag" (an original song written by Jones, Maltese, and musical director Milt Franklyn), which he sings in the cartoon. In a clip from a DVD special, Jones stated that he had come up with the name "Michigan Frog" during the 1970s and was inspired to add the "J." as a middle initial while being interviewed by the writer Jay Cocks.[5]
The Looney Tunes Golden Collection DVD credits Frog's original singing vocals to Bill Roberts, a nightclub entertainer in Los Angeles in the 1950s who had also done voice work for the 1948 MGM cartoon Little 'Tinker. (Roberts went uncredited at the time, as were most voice actors at the Warner Bros. studio who were not Mel Blanc, since only Blanc had a clause in his contract ensuring he would get on-screen credit.) In Another Froggy Evening, his voice was provided by Jeff McCarthy. In the cartoon From Hare to Eternity, Yosemite Sam digs up a treasure chest filled with carrots on a desert island; he also digs up Michigan J. Frog in his box who begins singing. However, Sam immediately shuts the box and tosses it away yelling, "Not in my picture!" Then, pokes his head out saying, "I hate frogs."
Michigan J. Frog made a cameo appearance in the New Looney Tunes episode "Misjudgment Day", voiced by Jeff Bergman. He appears at the end of the episode (including a futuristic version of the first three lines of "Hello! Ma Baby", which can also be heard in the background as Michigan croaks) as the one who sent one of his futuristic robots to destroy Bugs Bunny, and he later appeared in the show's second season intro.
A frog resembling Michigan appeared in the beginning of the 1988 Disney/Amblin film Who Framed Roger Rabbit at Maroon Cartoon Studios. The character also appears on the cover illustration (drawn by Chuck Jones) of singer-songwriter Leon Redbone's 1975 album On the Track.
Michigan makes his return in the Teen Titans Go! episode "Warner Bros. 100th Anniversary", voiced by Fred Tatasciore. He serves as the main antagonist, destroying the Warner Bros. studio and eliminating the majority of the studio's other characters as revenge for the Titans not inviting him to the studio's 100th anniversary party.
Years with The WB
Michigan J. Frog, again voiced by McCarthy, was the official mascot of The WB from its inception in 1995 until 2005. The network's first night of programming on January 11, 1995, began with Bugs Bunny and Daffy Duck wondering which one of them would pull the switch to launch The WB. The camera then panned over to Chuck Jones drawing Michigan on an easel; when Jones finished, Michigan leaped from the drawing to formally launch The WB and lands on Chuck's shoulder who then says "What's Up, Frog?"
Michigan also would usually appear before the opening of shows, informing the viewer of the TV rating. Before the beginning of Savannah, for example, the frog would sing a short monologue suggesting that "there's more comedy for the family Wednesday nights" and that kids should go to bed, meaning that the show coming on would be for mature audiences only. In later shows like Buffy the Vampire Slayer and Angel, the announcer would present a TV-PG disclaimer, though the frog still appeared as a neon sign.
On July 22, 2005, Michigan's "death" was announced by WB Chairman Garth Ancier at a fall season preview with the terse statement "The frog is dead and buried." The head of programming for The WB, David Janollari, stated that "[Michigan] was a symbol that perpetuated the young teen feel of the network. That's not the image we [now] want to put out to our audience."[6]
