Here are a few more, from a SCEA press release. I really don't get the point of many of them, but oh well!
More Playstation 2 software titles have been sold (51.6 million) than real Christmas trees bought by Americans each year (37.1 million).
Worldwide Playstation software shipments is more than double (869 million) the amount of cans of chicken noodle soup sold annually in the United States (350 million).
There are twice as many Playstation 2 games available (400) than there are different types of Barbie Dolls (200).
The number of Playstation hardware units sold life-to-date in North America (33 million) is more than double the number of times the average person blinks in one year (13,140,000).
