Ever wonder where the word SH*T comes from? Well, here it is

Certain types of manure used to be transported (as everything was
years ago) by ship. In dry form it weighed a lot less than when
wet, but once water (at sea) hit it, it not only became heavier, but
the process of fermentation began again, of which a byproduct is
methane gas. As the stuff was stored below decks in bundles you can
see what could (and did) happen. Methane began to build up below
decks and the first time someone came below at night with a lantern,
BOOOOM! Several ships were destroyed in this manner before it was
discovered what was happening. After that, the bundles of manure were
always stamped with the term "S.H.I.T" on them which meant to the
sailors to "Ship High In Transit." In other words, high enough off
the lower decks so that any water that came into the hold would not
touch this volatile cargo and start the production of methane.

Bet you didn't know the history of that word.
