Ever wonder where the word S**T came from? Well, here it is!
Certain types of manure used to be transported (as everything else was years ago) by ship. In dry form it weighed a lot less than when wet, but once water (sea water) hit it, it not only became heavier, but the process of fermentation began again which produced methane gas --- a very explosive by-product. As the stuff was stored below decks in bundles, you can see what could --- and did happen. Methane gas would build up below deck and the first time some sailor came below deck with a lantern

BOOOOM!
Several ships were destroyed in this manner before it was discovered what was happening. After that, the bundles were always stamped with "S.*.*.T." on them which meant to the sailors to "Ship High In Transit". In other words, store high enough off the lower deck so that any sea water that came into the hold would not touch this volatile cargo and start the production of explosive methane gas. Bet you didn't know the history of that word, did you? Neither did I. I always thought it was a golf term!
