Titanic Sinking

Alright, listen up, chucklehead. You see, the Titanic was a big ship that, like, sank to the bottom of the ocean, right? And when something "sinks in," it means you finally understand it. So, Titanic jokes "sink in" because they're about a sinking ship. It's a pun, get it? You probably don't, but whatever. You wouldn't know a joke if it slapped you in your stupid face.
