If you're not comfortable doing this, then find someone who is. Here's how to ground a 2 prong electrical plug.
Just turn the juice off at the breaker first. I plug in a radio, turn it up, then go into the basement and start flipping breakers until the radio goes off.
Click [url=www.selfhelpandmore.com/switch-outlet/composition-of-a-standard-electrical-outlet.php] here [\url], scroll about halfway down to the picture of the 2 outlets, with the numbered arrows.
1) Get a short piece of wire the same diameter/guage as what is attached to the plug, then strip off a short piece of wire so you have a bare wire about 2 or 3 inches long for the jumper.
2) Attach one end of the jumper around the silver screw #5 and the other end around the green screw #6. #5 is the neutral and #6 is the ground.
3) Attach the white wire to #3, which is the neutral wire.
4) Attach the black (or red) wire to #10 on the other side, which is the hot wire.
