What is what do you get when you cross a joke with a rhetorical question?

When you cross a joke with a rhetorical question, you don't get a punchline, but rather a statement that appears to be a question but doesn't require an answer because the answer is obvious or implied. This type of humorous statement is often used for its ironic effect and to challenge the listener's assumptions about a topic. For example: "Why do we park in a driveway and drive on a parkway?" or "If a tree falls in a forest and no one is around to hear it, does it make a sound?"
