The speaker plays along with the title's invitation to talk like a pirate, but the poem soon turns the game into something odder. The sea becomes a well, a deep source you lower a bucket into, and the speaker asks a captain to draw up stories from it. The stories they ask for are full of twisted logic: cards playing cards, money losing money, greed turning into a creed. Each phrase folds back on itself, as if the world of gambling and profit were feeding on its own appetite.
The final lines shift to a wistful, teasing tone. The speaker wants to hear France praised as "a fine country" and the tavern treated as a parliament, where talk stays calm and orderly. Judging by the imagery, there may be a gentle joke here about how much grand talk happens over drinks. The mood is playful but slightly wry, with a sense of wonder underneath the nonsense.
