The latest web distraction to steal a few minutes of my day: Weboggle.
There's a new game every 3 minutes or so, you can see scores from other users (some of whom are cheating as teams and others must be cheating somehow, I just know it), and with scores comes a list of words you didn't get (as well as words only you got, but that hasn't happened to me yet).
Everytime I'm there, I have to say "just one more game" at least three times before I can actually leave. If you try it out, I'm usually there as "Ken"; look for me in the lower half of the scores list.
