A bunch of Dell catalogs.

probably too many Styrofoam peanuts

Catnip?

Something overpacked?

That box is too small for a keyboard condom. I'm stumped.

Shroedinger.

Gwyneth Paltrow's severed head.

@evilzug: Bastard.

Dammit.

Schrodinger.

Air. At least in part. What do I win?

A defective - I mean new - I-phone . . .

the Karate Kid dvd collection?

Schrodinger's order from J. Crew. Did they get his size right? Until he opens the box, the answer is both yes and no.

Donuts?

I'm gonna say a cat.

since the dog is curious....I'm going to go with steak'ums

second guess is...a poorly packed AOL install cd

Air

It's the box that contains the Universe! Don't drop it or sit on it or anything.

Well...first you cut a hole in the box...

your SOUL. The cat stole it.

Can I guess what's in the cat?

A boat's a boat, but the mystery box could be anything. It could even be a boat!

I'm going to go with one paper clip and 5lbs of packing material.

Evil.

string, or nothing

A Cheezburger!

a red snapper -- very tasty

MayorBee beat me to the punch.

Anyways, it's food. My cats only stare like that at boxes if it's food. If it was anything else the cat would be lying on top of the box.

a wal mart nazi t-shirt

A present for me.

Keyboard codoms?

Something from the Something Store? Another box?

I'm not entering till I learn what the grand prize is for a correct guess.

an iphone bill?

This is a Ben Popken story - so it's probably something to do with the Grocery Shrink Ray. Am I right?

Hope.

Holy Grail.

The design looks like a box from Peet's (or at least what they used to look like - I'm too cheap to mail order Peet's any more). Did the Shrink Ray hit upscale coffee this time?

Nitrogen? Argon? Oxygen?

All of the recently banned commenters.

Consumerist.com t-shirts! Sweet. Send it over. thanks.

Maybe NSFW (it isn't where I work, but if where you work is strict...)

Is it the iPhone 3G or Mac 10.6 Snow Leopard which is why the cat's there?
(My guess was solely based on the huge amount of iPhone coverage on the Gawker sites as of late).

A pig, a fig, and a wig. Dig?

The soul of Marcellus Wallace.

Atoms

cupcakes

Bagels? God, I'm hungry...

A parallel universe?
