Honky Herring

If you think about it, humans are a long tube with legs and arms. We speak from our mouths and the other end of the tube that things come out of, well, that has other uses. But what if emanations from that other end could be used as a way of communication? There is no scientific evidence to date that humans use their bottom to communicate, despite what you might think. But fish do, perhaps. A Canadian study showed that herring seem to use the breaking of wind underwater to communicate with each other, and it wasn't just gas caused by what they had eaten. It's an odd way to communicate perhaps, but could explain why fish don't eat baked beans.
