Monkey Say (See?), Monkey Do

Has anyone heard, or know the meaning of this phrase?

"Monkey see, monkey do" is a traditional phrase used for commenting on someone's (often a child's) tendency to imitate whatever he or she sees someone else doing. Eric Partridge, Dictionary of Catch Phrases: American and British, from the Sixteenth Century to the Present Day, calls it a Canadian and U.S. catchphrase originating about 1925, "by c. 1950, also English, but . . . [used] rather to describe the learning of a a process, which, although performed thereafter with reasonable competence, is never actually understood."
