In irony of ironies, considering how poor I am, I woke up this morning and opened the shutters in my living room to see the sun rising from the east and said outloud (yes, I do talk to myself), "The world is my oyster." Of course, it’s not, and actually I said, "The woild is my oyster," mimicking a Mafioso or someone from stereotypical New Jersey/New York.
That got me to look up the origins of the saying, and it is indeed something from The Bard in The Merry Wives of Windsor.
Said Pistol to Falstaff therein:
Why, then the world’s mine oyster,
Which I with sword will open.
Maybe I’ll just fall on my sword. LOL
