Very crafty. However my favorite computer prank style is almost immediately clear you're being pranked but making it very hard to find how the prank works. For example, coworker in the previous place I worked at, noticed his mouse moves on its own. Classic prank, right? He found the wireless USB dongle and removed it. But it still kept on happening. By the time he realized it was a patched driver he threatened to murder us all a couple of times. I like this sort of prank because everyone is in the game, the victim included. They know they're being pranked and if it stops being fun you can end it gracefully.
