Hare Force is a 1944 Warner Bros. cartoon in the Merrie Melodies series, directed by Friz Freleng and starring Bugs Bunny and an old lady. Although the title is an obvious play on Air Force, the cartoon's plot has nothing to do with the military. The unit of Friz Freleng was the first unit besides Bob Clampett to use the definite design. Freleng made a slight modification, while this cartoon was in production. "As Time Goes By" is sung in this short by Sylvester and Bugs at different points.
