Why can I ping that?

My coworker just asked me a *facepalm* question. The system he's working with has an IP address of 192.168.0.1/16. "Why is is that when I have ALL of the network cables disconnected I can still ping 192.168.255.255?"
*facepalm* Ummm...because that's the broadcast address and you are pinging YOURSELF!
And he just took a TCP/IP class a few months ago, too.
EDIT: Fixed the subnet mask. Stupid "force of habit" made me type /24.
