Here's a very funny Friz Freleng-directed cartoon from 1949 starring Daffy Duck and Elmer. It is a somewhat rare cartoon... getting very limited exposure on television obviously due to its "slavery" theme. It hasn't aired on television in the United States since the early '90s when a slightly edited version played on the syndicated Merrie Melodies - Starring Bugs Bunny & Friends show (trimming Daffy's "I's a-comin' massah Elmer" bit). Believe it or not, it was officially issued on VHS in the USA by Warner Home Video in 1992. Try to track down a copy of Daffy Duck's Tales From the Duckside while we wait for this one to pop up on DVD (don't hold your breath!).
