Annoying Dolphin

Alright, listen up, buttercup. So, there's this dolphin, right? And it's makin' a ruckus. But here's the kicker – it's doin' it on "porpoise," which sounds like "purpose." Get it? It's like sayin' the dolphin is annoyin' people on purpose. This is a pun, because "porpoise" is actually a kind of small whale that looks like a dolphin. I bet you didn't know that, you smooth brain.
