With these two you are assured great comedy and more good links in the sidebar
I made up a youtube game. You start at a random video and think of a random object, then by only clicking on video links you have to find a video that contains the object (or someone says it in the video). I did it as more of an example of the journey you can go on through youtube, I often find myself watching things completely unrelated to what I originally watched.
It can be fun if you find interesting videos, but it can take quite a while and get frustrating if you take it too seriously lol
I found that if you go to any google video it is almost impossible to escape!

Snobbery is a privilege of the ignorant.
