One Frostbite Falls citizen who shows up at the committee meeting is Miles Standoffish, a turkey farmer dressed in Pilgrim garb. This character spoofs Myles Standish, the English military officer who led the Pilgrims of Plymouth Colony in the 1600s. Tales of the Pilgrims and their Native American neighbors form the basis of the American holiday of Thanksgiving, which is traditionally celebrated with a turkey dinner.
Part of the story takes place in the comically-described "Lower North Pakistan". At the time this cartoon was made (the early 1960s), there was such a place as East Pakistan. From 1955 to 1971, East Pakistan was the eastern wing of Pakistan, made up of the eastern Bengal territory located on the opposite end of the Indian subcontinent from the larger western portion of Pakistan. (The territories of the British Empire on the subcontinent were granted independent rule in 1947 and divided along religious/cultural lines into India and Pakistan, with Pakistan split into sections on either side of India.) What was known as East Pakistan is now the independent nation of Bangladesh.
