It's not all that funny, but the clip does remind us about the subjective nature of interpretation. The background music offers the same lesson. The tune is "Oh, My Darling Clementine" a western ballad from the late 19th century, in which a California gold miner loses the love of his life (Clementine) in a drowning accident, before finding some consolation with her "little sister." In the late 20th century, Uncle Moishy appropriated the melody for his enduring classic "Dip the Apple in the Honey (Make a Brocha Loud and Clear.)"
When its original audience heard the tune that plays behind this 2011 clip, they were reminded of the miner's immoral affection for a minor. Today, among Orthodox Jews at least, the same tune evokes holiday thoughts and nostalgic memories of apple-toting toddlers, splattered with honey.
As always, meaning exists merely in the mind which contemplates it. (David Hume, paraphrased.)
