In the ridiculous (and great) film The Adventures of Buckaroo Banzai Across the 8th Dimension, there are many questions to be asked. The movie asks one of them itself: "Why is there a watermelon there?" I am referring to a scene in which New Jersey, played by Jeff Goldblum, notices a watermelon between two panels. The scene is quite funny, and the question is never answered. Are there in- and out-of universe answers to this question, besides "It's just a joke?"
