Here's a joke that includes all the elements you mentioned: One day, a rabbit, a bear, and a wolf stumbled upon a magical field of carrots. Excitedly, they started munching away, each trying to eat more carrots than the others. As they were eating, a fairy appeared and said, "Since you're all enjoying the carrots so much, I'll grant each of you a wish." The bear spoke up first and said, "I wish for a big, juicy steak to go with all these carrots." The fairy granted the bear's wish and disappeared. Next, the wolf said, "I wish for a pack of fellow wolves to share in this feast." The fairy granted the wolf's wish and disappeared once again. Finally, it was the rabbit's turn. The rabbit thought for a moment, and then said, "I wish for the bear to become a vegetarian and the wolf to become a carrot." The bear and wolf looked at each other in shock, but before they could react, the fairy appeared and granted the rabbit's wish. The bear suddenly lost all taste for meat and the wolf turned into a giant carrot. Moral of the story? Be careful what you wish for!
