I would wish for
1. Eat anything I wanted and not get fat or have any ill effect on my body.
2. Have a canteen that holds an infinite amount of some liquid (probably Mt. Dew or something considering my first wish I could drink all I wanted.)
3a. I would ask for 100 more wishes.
3b. If 3a can't be granted, then I would wish... for... a billion dollars.
yeah, I'm selfish in my wishes, but I don't care lol. Plus. If I had a billion dollars, I'd invest and stuff and if the return was good I'd go into philanthropy, so I guess I'm not all that bad.
