Regret
An old lady is rocking away the last of her days on her front porch, reflecting on her long life, when--all of the sudden--a fairy godmother appears in front of her and informs her that she will be granted three wishes.
"Well, now," says the old lady, "I guess I would like to be really rich."
** POOF *** Her rocking chair turns to solid gold.
"And, gee, I guess I wouldn't mind being a young, beautiful princess."
*** POOF *** She turns into a beautiful young woman.
"Your third wish?" asked the fairy godmother.
Just then the old woman's cat wanders across the porch in front of them. "Ooh, can you change him into a handsome prince?" she asks.
*** POOF *** There before her stands a young man more handsome than anyone could possibly imagine. She stares at him, smitten.
With a smile that makes her knees weak, he saunters across the porch in his catlike way and whispers in her ear, "Bet you're sorry you had me neutered, aren't you?"
