robotic shark?

i want to build/buy/accuire a robitic shark submarine that can easily be controlled by one person. i think it would be cool to shark through some deep waters. this obviously would be the one thing that could make me better than everyone on the planet... somebody says "hey i just built a house" yeah? well i live in a shark. see what i mean you just cant beat it. the ony thing that could possubly beat it is if your turds were just 100% solid gold. witch then you just sell your poop and be super uber rich!
