First YouTube Video EVER Celebrates Its 5th Anniversary: Send Us Your Favorite Videos!

It's been a landmark week: we celebrated the 40th anniversary of Earth Day, the 50th anniversary of the birth control pill, and the 20th anniversary of the Hubble Telescope.

April 23 marks a lesser known, but nonetheless important, event: the fifth anniversary of the first video uploaded to YouTube.

YouTube was founded February 14, 2005, but the first video to hit the site--a 19 second clip of YouTube cofounder Jawed Karim at the San Diego zoo--didn't come until April 23, 2005.

Check out the first-ever YouTube video below, then we want to hear from you: What is your favorite YouTube video ever? And why?
