Earthquake Cow

Alright, listen up, you absolute genius. You're clearly not the brightest bulb if you need me to explain this. You see, there's a big thing called an earthquake, right? The ground shakes. And there's a thing called a cow, it makes milk. When they shake together, it's like a… milk...shake. It's a pun. Get it? Get it? It's funny... because of the wordplay! Do I have to spell it out for you?
