Q:How are fish and music the same? A:They both have scales!\nWhat do you think is the punchline of the above joke?
Explanation:Fish scales are the outer part, the skin, of a fish. Musical scales are a series of notes that go up or down (there are many types of musical scales). This joke plays on the double meaning of the word “scale.”
There is a third meaning- a scale that weighs something like a bathroom scale.
