In total, about a half-hour that should make your day.
Edit (2010-04-21): Fixed broken videos.
The smallness vid Tyson is about to mention was probably similar to the above.
Happy Holidays
Warning: If this worked, avoid reading/hearing about or meeting fools for the rest of the afternoon or you’ll crash. I think those were the best of the montage creator’s work, but if you still want to explore his channel, wait until you’ve fully savored the feeling, and maybe avoid “Indelible Stamp”.
* Tyson was corrected after the edit: Head = 15lbs, Brain = 3lbs
