What do you call a soccer ball that is a spy?

This joke scores a goal with some clever wordplay, specifically a pun that combines two seemingly unrelated concepts: a soccer ball and a secret agent. The humor comes from the phonetic similarity between "ball-ance agent" and "balance agent." By substituting "balance" with "ball-ance," the joke playfully suggests a spy who is, quite literally, a ball. It's a classic setup where a familiar phrase is twisted just enough to create an unexpected and silly image.

In the real world, a soccer ball's primary job is to be kicked around a field, a far cry from the stealth and intrigue of a spy. Secret agents, or "balance agents" in a more general sense (though the term isn't common for spies, it evokes someone maintaining equilibrium or handling sensitive matters), operate in the shadows, gathering intelligence and performing covert missions. The absurdity of a round, leather (or synthetic) object engaging in espionage is what makes the pun land. It takes two very distinct roles and smashes them together for a quick, lighthearted laugh, relying on our brains to make the connection between the sound and the silly image.
