These Disney chipmunks made their first appearance in 1936 , but were not named Chip and Dale until this particular Donald Duck cartoon that debuted today in 1947. Their appearances became more frequent when Disney decided to use them as a foil for The Donald. Dale is the more dimwitted of the two, and Chip concocts all their brilliant plans to thwart Donald. Their main goal in life is to amass a great stockpile of acorns. They have nothing to do with the Chipendale dancers, whose nuts are of a different order.
