A merchant captain and several of his officers were returning to the ship after an evening of partying ashore. As they climbed the gangway, the captain threw up all over himself.
Pointing to an apprentice seaman above, he shouted, “Give that man five days in the brig for vomiting!”
The following morning the captain was checking the log and saw that the young seaman had been sentenced to ten days and asked the chief mate why.
“Well Sir, when we got you undressed we found that he’d also taken a dump in your pants. “
