Black Box

Black Box is the ultimate practical joke application for iPhone and iPod Touch. Gone are the days you had to stand device in-hand to trigger those rude or funny sound effects. Now you don't have to let them see you coming! Black Box uses Twitter, the popular micro-blogging service, as a remote control for the ultimate prank; load any funny sound you want, assign a keyword to it and fire it anytime via Twitter – all done with a computer or mobile device of your choice.
