Simulating a Linux Kernel panic

I was once asked a question "How can you simulate Kernel Panic" by someone. Not sure why you would want to do it, probably to test if your monitoring tools report things properly.
Anyways after LOT of googling around I found a link which suggested the way, here's how you can do it (as super user)

echo c > /proc/sysrq-trigger

As soon as you hit the above command, the machine freezes. To check if machine really froze because of a kernel panic check /var/log/messages
