My equator crossing was on the Caronia, not the one that's out now but her predecessor, the "Green Goddess, affectionately called by her crew the "Green Dragon". I was a kid, just 21 and we got the worst of it. The older passengers on this world cruise didn't even have to get wet. We were told to dress casually, dumped in the pool with our clothes on, greeted by a "Sea Urchin" a cresman dressed from his neck down in a variety of grass skirts covered with engine oil. Then we were heartily embraced and kissed by the sea urchin. The clothes were ruined and it took about a week to wash the grease off. Actually, it was fun. Somewhere around my apartment I've got a certificate saying I crossed the equator with due homage to King Neptune.
