Quarter Pounders would be fat free.
Diet Coke would be chalk full of vitamins and minerals.
Running would be fun!
Cell phones would be free, including texting. Oh, and gas too.
My weight would stabilize at about 15 lbs less than where it is now, and stay there. Forever. No matter what.
Oh, and world peace, healthy children, money grows on trees, yada yada yada.
Anyone else? What's would it take to rock your world?
