Finding: BUSTED

Explanation: The brown note, also known as the disco dump, is a subsonic frequency around 9 Hertz (Hz) that supposedly rocks so hard, it causes people to lose control of their bowels. Conspiracy theories about this nauseating tone go back to before World War II, and some people believe government forces belt out inaudible brown notes to disable unsuspecting audiences.

MythBusters Adam Savage and Jamie Hyneman tracked down some alleged brown-note audio files online and blasted them at various frequencies, attempting to hit the not-so-sweet spot. Adam sat at the center of the 24-speaker brown-note symphony, and his body absorbed all the brown-note vibrations projected at an undetectable 5 Hz up to 20 Hz.

When none of those frequencies struck a chord with Adam's stomach, the MythBusters team pumped up the volume to a deafening 128 decibels. Adam could feel the music pumping against his chest, but it had no physical effects below the belt.

All of the brown-note frequencies failed to stir the MythBuster's bowels, busting the myth - and preserving Adam's dignity.
