The title of this episode is a word play on an old saying "Monkey see, monkey do", which is a pidgin-style saying that appeared in American culture in the early 1920s. The saying refers to the learning of a process without an understanding of why it works. Another definition implies the act of mimicry.
Whether intentional or mere coincidence, this episode seems to share elements with the comedic murder mystery The Hidden Hand (1942). Most notably, as in the movie, Milton Parsons plays a scheming butler, a will is played on a vinyl record, and a plot point involves lacing a decanter of alcohol with knock-out pills.
