The one I have up right now is my Quit Smoking Calculator and has been online for a few years. It gets a fair amount of traffic and I've even received email from people saying how much it has helped them.
It calculates how long you have been not smoking. How much money you have saved. And, how many cigarettes you have not smoked.

The NASCAR Fantasy Team Name generator helps you out in selecting a name for your fantasy NASCAR team. It's a lot of fun.
The Band Name generator will create endless amounts random fun whether you are actually in a band or not.
On the little more geeky side, I also have a MD5 and SHA1 generator.
