The "That's a paddlin'" meme features the character Jasper Beardly from a 1995 episode of The Simpsons titled "The PTA Disbands." In the scene, Jasper acts as a substitute teacher and warns students that almost any minor infraction—like staring out the window or wearing school shoes—will result in corporal punishment. The phrase became an internet sensation in the mid-2000s, used as a humorous way to call out specific behaviors or "rules" on forums and social media. Today, it remains a go-to template for listing arbitrary consequences in a deadpan, old-fashioned style.
