Wanna have a good laugh at your friend and his misbehaving computer?Then these prank programs would be handy;the victim is sure to get gooseberries!They're purely for fun and not meant for any malicious intention.Try these out on not-so-computer savvy people,they wont be able to find out whats causing the pc to go mad.Recommended for the females! ;)

Schitzo Mouse
Causes the mouse to jump around like it is crazy.

ButtonShy
Causes the mouse to shy away or jump from most buttons (even the Start button).

RudeCDTray
Causes the CD-ROM drive to open up and give you a rasberry.

FallingIcons
Causes the desktop icons to fall down the screen, no matter how many times the victim tries to put them back in place. This prank is nice so there is a FallingIcons button that pops up on the system tray. Just click the button to return the icons to their prior positions.

Note:Symantec Coporate detected this a malware but I'm fairly sure that its otherwise.
