Maybe if George Clooney & Mark Wahlberg had laughed more, they'd have made it.

The frigid North Sea between Great Britain and Scandinavia is full of two things: oil buried deep under the seabed, and giant waves roaming the surface. I don't think the captain of this large-but-not-oil-tanker-sized ship was looking for oil, but he definitely found some killer waves—and then proceeded to plow straight through them (you have to, or else risk being knocked on your side) while laughing like a madman. Normally, "laughing like a madman" is a euphemism, but this guy is laughing while several thousand tons of water come crashing at him, so...yeah, like a madman.
