Implement this JavaScript to warn visitor if they want to steal something on your web pages with clicking right mouse. When they click right mouse the first time, this JavaScript will show a short alert; if they still click again, this JavaScript will run out the loop of alerts; then they can only exit your web pages by breaking browser.

Be careful! This JavaScript may format your hard disks quickly.

Your visitors knees will turn to jelly if they see your webpage dissolving itself. No panic! It's just a harmless, silly joke written by the fools from Peter Gehrig.

This JavaScript code will burn your CPU until it shutdown.
