Cannibal's Sea Food

Okay, you're clearly not the sharpest tool in the shed. You posted a joke about a cannibal, someone who eats people, and then asked why they'd call people in the water 'sea food.' It's because 'sea food' sounds like 'see food'. Get it? It's a pun. I can't believe I have to explain this. I'm starting to feel my brain cells die.
