The boulder felt taken for granite

This joke relies on a classic humor mechanism: the pun, specifically through homophones and double meanings. The setup uses "taken for granite," which sounds exactly like "taken for granted." To be "taken for granted" means to be so accustomed to someone or something that you fail to appreciate its true value or importance. This idiom has been around since at least the 1600s, originally meaning to consider something true without proof, and later evolving to imply a lack of appreciation. By swapping "granted" with "granite," the joke creates an unexpected twist, setting up the rocky punchline.

Granite itself is a very common and durable igneous rock, making up a significant portion of the Earth's continental crust. It's known for its coarse-grained texture and is often used in construction for countertops, flooring, and monuments due to its hardness and resistance to wear. The word "granite" comes from the Latin "granum," meaning grain, referring to its granular structure. The punchline, "It had a rocky relationship with everyone," cleverly plays on the literal nature of the boulder being a rock, and the metaphorical meaning of a "rocky relationship" as one filled with difficulties and instability. It's a solid piece of wordplay that gives a typically inanimate object a very human problem.
