Referred to bySteven Spielberg as "theCitizen Kane of animated film", this1955Chuck JonesMerrie Melodies short featured none of the regularWarner Bros. stable, instead telling a standalone story about a construction worker who discovers a live frog inside the cornerstone of a building he's helping to demolish. To his amazement, the frog pulls out a little top hat and cane and starts to sing and dance. The construction worker naturally expects to strike it rich from his discovery. Unfortunately, the frogrefuses to perform in front of anybody else. At the end, after becoming destitute and homeless, the man puts the frog into the cornerstone of a new building, and a flash forward reveals that a man of the future will soon suffer the same fate.
Told entirely without dialogue (except, of course, for the singing). The frog would later be named Michigan J. Frog, after the only original song from the short, "The Michigan Rag", and become the mascot forthe WB network.
This cartoon has been named number 5 ofThe 50 Greatest Cartoons, and was added to theNational Film Registry in 2003.
