Forget the whoppee cushion. Pranking has gone hi-tech with this USB Computer Prankster that will turn caps lock on and off, make random mouse movements, and type out random text:

Handily, the Prankster features a time delay setting, so that after installing it, you can make your getaway safely before it startmisbehaving.

The Prankster is highly annoying, but itll never activate the Enter key or close or save documents, so it’s mostly mischievous, not super-dangerous.
