This is a true response to an exam question:

Q. A cruise ship, made up of tons of steel, is able to float on water. Steel is much denser than water, so how is it that ships of enormous size are able to float?

Response:

They can't float. Remember the Titanic. Anyone who pays $3,000 to go on a boat for a week with a bunch of people they don't know deserves the cruelest form of death available. Slowly sinking to the bowels of oceans in their contemporary Hawaiian plaid shorts as god takes the burden of life away from those who are not fit to observe it. Perhaps the only force allowing remote floatation is the plethora of bombs strategically implanted in the hull of the ship causing a massive upward thrust to counteract the weight of their inconclusive stupidity. I sit back with my Miller High Life on the cusp of the island and watch and I think what a waste of explosives and steel and 40 year old women who peak to the bottom of their fat heart-burned husbands sexual pendulums at the bottom of their swing. It does not get any better than this.
