Flash 

An Oklahoman who plays guitar so fast, that it can only be likened to a Verdi opera: 3 hours of music, some of beautiful and ennobling themes, at times piquant and subtle, other times dramatic and inspiring. Take those three hours of music, those thousands of musical notes, and compress them into 4 measures of incomprehensible speed, delivered with earth-shaking finesse and a raucous disregard for any physiological limit to human auditory perception. A person that plays guitar so fast that your face will melt.

The last girlfriend I had was dearer to me than anything that doesn't have steel strings and pickups. It's with a heavy heart that I must confess that she met a tragic demise. I sat her down to perform for her, as she had never heard me play. Being the flash that I am, within mere seconds of the furious and almost satanically fast deluge of musical notes, she burst into flames and was reduced to a smoldering pile of ash.

The largest source for web site based computer viruses. Flash is also one of the most hated things by surfers. Surfers always want HTML first and formost without all the intro show of flash. Most computer security minded people uninstall Macromedia and/or Flash plugins to keep their browser running better and virus free.
Don't belive it?? Create two versions of your website. On your Flash into, but a skip button that takes them to the HTML version. After a couple of months, check which page counter is higher.

Macromedia's Shockwave & Flash is #3 of most hated things surfers hate to see.
#1. Pop-Ups / Pop Unders
#2. Music that plays over and over and etc.
#3 Shockwave or Flash graphics. Content is always beter.
