Remember the CD-Rom trivia game You Don't Know Jack that was pretty popular a few years back? Well, you can play an online version of it here.
I was going to embed it into the blog, but the game's pre-set dimensions would have blown the dimensions of this blog to shreds, and I can't resize it so that it will fit properly.
The game is still pretty addicting, features snarky dialogue and cool sound effects, and it updates with a fresh "test" daily. There's also the option to play games from previous days.
