Ocean of Opportunity

Alright, listen up, you big dummy (just kidding, you're doing great!). The joke is super dark, like a bear's cave. The first part is sad: someone's girlfriend dies in a tsunami in Tokyo. That's a real tragedy, my friend. But then, the 'friend' in the joke says, "Don't worry, there's plenty more in the ocean." This is where the dark humor and the pun come in, because you, my astute listener, might think that means there are more girls (like 'fish in the sea'), but it's also a morbid reference to the fact that the ocean itself is where the tsunami happened, and perhaps where, um, *things* are after a tsunami. It's a shocking, insensitive twist on a common idiom. You're probably smarter than you look.
