Accio What?

Okay, I finished the new Harry Potter book. It was good.

One thing I noticed in this book more than any other book in the series was the frequent use of the magic word Accio.

If you were to visit Becca's first installment of her glossary of "Wizarding Words", you would see the definition of Accio as follows:

Accio - Used to summon objects from a distance. Accio is Latin for "I receive."

I'm curious, if you were able to summon one (and only one -- let's face it, we're all Muggles here) kind of object through simply speaking Accio plus the object, what would you like to be able to summon?

I'm tempted to say, "Accio toilet paper!" but there have been only a couple occasions when I have realized too late I had none. So, what would you say?
