I came across this great Dutch web site with 10 crazy facts about the universe. It's a great (quick) list if you're in the mood to laugh and ponder your own existence.
Example: "Every breath you take contains an atom breathed out by Marilyn Monroe. This is because atoms are very small. It would take 10 million, laid end to end, to span the width of a single period on this page."
This article is accompanied by a great video featuring Marcus Chown of New Scientist.
