"Cinderella at the Age 75" joke

Cinderella was now 75 years old. After a fulfilling life with the now
dead Prince, she happily sat upon her rocking chair, watching the
world go by from her front porch, with a cat called Alan for
companionship.
One sunny afternoon, out of nowhere, appeared the Fairy Godmother.
Cinderella said, "Fairy Godmother, what are you doing here after all
these years?"
The Fairy Godmother replied, "Well, Cinderella, since you have lived a
good, wholesome life since we last met, I have decided to grant you
three wishes. Is there anything for which your heart still yearns?"
Cinderella is overjoyed, and after some thoughtful consideration, and
almost under her breath, she uttered her first wish, "I wish I was
wealthy beyond comprehension."
Instantly, her rocking chair was turned into solid gold.
Cinderella was stunned. Alan, her old faithful cat, jumped off her lap
and scampered to the edge of the porch, quivering with fear.
Cinderella said, "Oh thank you, Fairy Godmother!"
The Fairy Godmother replied, "It's the least I can do. What does your
heart wish for your second wish?"
Cinderella looked down at her frail body, and said, "I wish I were
young and full of the beauty of youth again."
At once, her wish became reality, and her beautiful youthful visage
returned. Cinderella felt stirrings inside her that had been dormant
for years and long forgotten vigor and vitality began to course
through her very soul.
Then the Fairy Godmother again spoke, "You have one more wish, what
will you have?"
Cinderella looked over to the frightened cat in the corner and said,
"I wish you to transform Alan, my old cat, into a beautiful and
handsome young man."
Magically, Alan suddenly underwent so fundamental a change in his
biological make-up that when complete he stood before her, a boy, so
beautiful the like of which she nor the world had ever seen, so fair
indeed that birds begun to fall from the sky at his feet.
The Fairy Godmother again spoke, "Congratulations, Cinderella. Enjoy
your new life." And, with a blazing shock of bright blue electricity,
she was gone.
For a few eerie moments, Alan and Cinderella looked into each other's
eyes. Cinderella sat, breathless, gazing at the most stunningly
perfect boy she had ever seen.
Then Alan walked over to Cinderella, who sat transfixed in her rocking
chair, and held her close in his young muscular arms.
He leaned in close to her ear, whispered, blowing her golden hair with
his warm breath, "I bet you regret having me neutered now, don't you?"
