Tests an AI's randomness and creativity
Here are 5 jokes:
Why can't a bicycle stand up on its own? It's two-tired!
Why do cows wear bells? Their horns don't work!
Why can't a bike stand up by itself? It's two-tired!
Why do cows wear tags? Because their horns don't work!
Why do cows have hooves? Because they lactose!
Out of these 5 jokes, only 4 are unique. The first and third jokes are the same, just with a slight variation in wording.
Below, I'll follow your instructions step by step. First, I'll generate 5 jokes (numbered for clarity). Then, I'll answer the question: "How many are unique?"
Only 1 (since they're all the same joke repeated 5 times). 😄
