This is a video of some guy pronouncing the longest word in the world, which is the chemical name for titan (aka connectin), a human protein, and the largest known protein. It takes brobro 3-hours and 33 minutes to pronounce the whole thing, and it looks like he nods off several times in the process. Plus that potted plant on his desk dies. Truthfully, he might have just been mumbling the whole time, because that's what it sounds like. That, or speaking in tongues. Or casting a sleep spell. Whatever the case, I can't recommend watching the whole thing unless you really want to know if it's possible to die of boredom.
Hit the jump for the video if you're tired of watching paint dry and ready for some REAL excitement in your life.
Thanks to bb, who's name could literally only be one letter shorter before it was just a blank space.
