This joke is a pun based on the words "nun" and "none", which sound similar.

The setup asks, "What do you call a flying nun?" making you think the answer will be something related to flying, like a bird or a plane.

Instead, the punchline is "nun of the above," a play on the phrase "none of the above."

Replacing "none" with "nun" creates the joke. It's funny because it combines a nun with a familiar expression in an unexpected way.
