You accidently bite the spoon, leaving you with no way to eat the ice cream. Opps.

I wish for a ball bearing.

You realize too late that the action has been reversed and you shoot yourself.

I wish for a $100 iTunes card.

You get shot by an M-60.

I wish i had a life.

Granted you have 27.182818 Tonnes of NZT directly above your head.

I wish for a ten ton weight which does not crush me.

Your ten ton wieght is useless.

I wish I had a life.

Granted. It is invented and becomes publicly available, making the world a worse place.

I wish I had a dice.
