Giving clowns a run for their money

First, an admission. I have been awake for almost 24 hours and might be delirious....however, after years of internal debate i have decided that i never want to go deep sea diving. i mean, think about it, you're voluntarily submerging yourself under hundreds of feet of water basically breathing through a piece of plastic. Additionally, you are surrounded by fish that will scare you, given the chance. and i'm not talking goldfish here people, these things have teeth. teeth that are just waiting for a person sandwich.

So lets count how many things can go wrong with this scenario........
