Guybrush Threepwood and Herman Toothrot on Dinky Island

Herman: "If a tree falls in the forest and no one is around to hear it, what color is the tree?"
Guybrush (after exhausting all colors): "All colors?"
Herman: "Exactly. Now, what has this experience taught you?"
Guybrush: "That philosophy isn't worth my time."
Herman: "I'm very impressed. It takes most people years to reach this point."
