I Only Have Eyes for You is a 1937 Merrie Melodies animated short film directed by Tex Avery with an all-bird cast, and based on the song of the same name. The protagonist (voiced by Joe Dougherty), who drives an ice-delivery truck, is wooed by a homely spinster bird (voiced by Elvia Allman) who hopes to entice him with her culinary talents. The iceman, on the other hand, is only interested in Katie Canary (a Katharine Hepburn impression voiced by Sara Berner), who only wants to marry a radio crooner and rebuffs his overtures to the point where she prefers ordering a refrigerator. The iceman, in order to win Katie, hires a voice imitator, Professor Mockingbird, to simulate crooners from the back of his ice truck while the iceman lip-syncs. The scheme eventually backfires when Professor Mockingbird turns blue from the extreme cold in the ice truck. Katie marries the Professor, being sufficiently impressed by his crooning ability (while replacing her radio with an electric refrigerator), while the iceman is finally won over by the spinster's cooking and baking and presumably marries her.
