Checking back on Mayotte posts.

Bakers thanks for putting my dig in notables.

This one is for keks only: The Brown Note CONFIRMED

In patent US6017302 it is shown that an audio signal applied at a certain specific frequency close to 1/2 Hz can produce a "knot" in the stomach and sudden loose stool.

The Brown Note is real, and the method do create it is patented by Hendricus G. Loos.

Hahahahahahahahahaaha.

FWIW Mythbusters tested 5 Hz. They were off by a factor of 10.
