Granted. You're now the best cook in the entire world. Every other cook comes to you 24 hours a day and demands lessons from you. But since none of them got their cooking through magic wish giving powers, they get frustrated that you can't teach them anything. After a month of this you're stabbed to death by a stale Italian Bread Loaf.
I wish that someone would make a bacon meatball garlic bread with pizza in the middle sandwhich. So I could eat it.
