Chip and Dale (also rendered as Chip 'n' Dale or Chip an' Dale) are two chipmunk cartoon characters created in 1943, at Walt Disney Productions. Their names are a pun based on the name of the famous 18th-century cabinet maker Thomas Chippendale. This was suggested by Bill "Tex" Henson, a story artist at the studio.
Chip is the logical schemer while Dale is the goofy, dim-witted one. Originally the two had a very similar appearance but, as a way to tell them apart, some differences were introduced: Chip has a small black nose (somewhat resembling a chocolate "chip", as befitting his name) and two centered protruding teeth. Dale has a larger, dark red nose and it is his canine teeth that are exposed. Dale has a very strong sense of humor while Chip is more of the safe, focused one. Chip is also depicted as having smooth, short hair atop his head while Dale's is ruffled.
In most cartoons they are either antagonists against Pluto or, more frequently, against Donald Duck. In the 1950s, they were finally given their own series, but only three cartoons were made: Chicken in the Rough (1951), Two Chips and a Miss (1952) and The Lone Chipmunks (1954).
