You're The Man Now Dog - Revisited
That's right, once upon a time as a junior at CU; I remember forwarding out a link to You're the man now dog.com. I had no idea what it would turn into! It turned into a movement of sorts, the owner of the site started YTMND.com a site hosts and lists all sorts of 'YTMND' pages -- pages like the original with a basic picture (or animated picture) and a looping sound bite playing in the background.
Check out some great YTMND pages!
