Apparently the PS3 comes with cinder blocks, because how else can you explain what they could be hiding deep inside that cardboard case. As PS3Land writes:

From the looks of the box, you may need to bring a friend to help carry your PS3 home!

I wouldn’t let my friends touch my new PS3. They’ll steal my console like they stole my bike.

Edit: Clearly Biggs has a mammoth head if it is as big as that PS3 box. – Blake
