A course in troll sockpuppets/Insecure troll
One of the easiest trolls to create is the insecure troll. He's desperate to compensate for something and doesn't have a girlfriend. So in between rounds of downloading pornography he tells everyone what a great big man he is. Nobody's fooled but that doesn't stop him from trying.
Instructions
editTo build the insecure troll, mark off two inches from a regular ruler onto a piece of cardboard in quarter inch increments. Trim and attach to the troll hand with basting stitches. Or substitute a magnifying glass.
Poor little troll...
