Come to think of it, when I was a kid I wrote a bunch of little apps and packaged it together as something called "prank pack". It was all little prank apps, like fake format, error messages etc. I put it on CNET download.com, which used to be free. I never even considered the fact that April fools was around the corner. The app got like 60 thousand downloads overnight. Was hosted on Tripod so I got shut down for running my bandwidth limit. Man, if I would have been better setup with a real web host and adsense I would have made a killing.
The app actually made top 10 downloads on major sites like MSN.com, CNET etc... It was an awesome feeling.
LOL I googled it and found it:
http://rsscripts.tripod.com/reliexec/pp.htm.
That was a re-release though, that was not the official site. Man that site is old though, I totally forgot about it lol.
I should download and archive that site somewhere. I'm actually surprised it's still up.
