i hate to totally cop boing boing when i'm already pulling the link from their site, but i just don't know how to say it any better than they did:
"This experiment alone was worth the entire cost of the space program"
(it's all great. but make sure you get to the last 45 seconds or so.)
and while i'm out pillaging...
also from the boingers:
the election quote of the day
"Karl Rove is not Aleister Crowley, Severus Snape, Darth Vader or Satan. You can kill him by ensuring your vote is counted and being vigilant at your polling station."
and palindrome pandemonium!
including instant manske classics like: "Dog sex at noon taxes God."
