From the doc: 'Random Burper is just that, a
hidden software program that will play gross burp
sounds randomly every minute until closed. There
are many different burp sounds that our software
has to choose from, listen long enough and you
might even hear a small fart. Our software has an
added feature of turning the internal Windows
volume to maximum just before burping, then
restoring it back to the original settings. Place
Random Burper on an unsuspecting office worker and
watch them become red with embarrassment. This is
a must have prank to play on that conservative
worker in your office.'
