Every time I see a video with a title like this, like say “driver falls asleep at the wheel,” or “amusement park ride gone wrong,” or “adorable kitten murders owner by clawing out her appendix,” I think, why did I watch that? I wasn’t afraid of driving or amusement park rides and ESPECIALLY NOT KITTENS, but I guess now I can never go near any of those things again.

The same can be said for this video, where the most relaxing vacation idea ever suddenly turns terrifying. You’ll notice that everyone goes from pleasantly enjoying a meal in the dining hall to being thrown from one end of a floating city to another.

I’d heard of sea-sickness, but never sea-blunt-force-trauma, until now. Thanks, LiveLeak. Really. Thanks.
