Captain’S Log
The first-mate on a ship decided to celebrate his birthday a bit too much with a night on the town, where the ship had docked. The following morning he was still drunk; realising this, the captain wrote in the ship’s log ‘The first-mate was drunk today.’
The first-mate pleaded with the captain to erase the entry, as he knew this would affect his prospects of promotion to captain.
The captain asked the first-mate if the entry in the ship’s log was true.
The first-mate agreed that the statement was true.
At this, the captain explained that since it is true, it has to go in the ship’s log.
A few days later it was the first-mate’s responsibility to make the entry in the ship’s log, he wrote ‘The ship seems in particularly good shape – the captain was sober today.’
