Just thought of a cute way to corrupt the "multiple wishes" wish.
Player: I cast wish.
DM: What do you wish for?
Player A: Infinite wishes!
DM: The magic courses through you, changing the fabric of reality... and a scroll appears before you.
Player A: I pick it up.
DM: As soon as you pick it up, you find yourself compelled to unfurl the scroll. It is a scroll of Wish. Without hesitation, you begin reading the magic words. The scroll bursts into magical flame. Magic courses through you, changing the fabric of reality... and your lips, of their own accord, mouth the words: "I wish for another wish." and a scroll appears before you.
Player A: uh... I pick it up?
DM: As before, you are compelled to read the scroll, and as before, you are compelled to wish for another wish. A scroll appears before you.
Player B: Wait, I got this... I pick it up!
DM: aha! You feel compelled to read the scroll. Despite your complete lack of magical knowledge, you find yourself going through the motions of casting a spell. It works! Your lips continue of their own accord. "I wish Player A had another wish!" A scroll appears before player A.
Either that, or a time loop.
