One Froggy Evening is a 1955 American Technicolor animated musical short film written by Michael Maltese and directed by Chuck Jones, with musical direction by Milt Franklyn. The short, partly inspired by a 1944 Cary Grant film entitled Once Upon a Time involving a dancing caterpillar in a small box, marks the debut of Michigan J. Frog: an anthropomorphic frog with a talent for singing and dancing that he demonstrates for no one except whoever possesses the box wherein he resides. This popular short contained a wide variety of musical entertainment, with songs ranging from "Hello! Ma Baby" and "I'm Just Wild About Harry", two Tin Pan Alley classics, to "Largo al Factotum", Figaro's aria from the opera Il Barbiere di Siviglia. The short was released on December 31, 1955, as part of Warner Bros.' Merrie Melodies series of cartoons.
