1. record your wife/girl friend/female friend on cam or download some movie of a chick infront of her pc and cam.
2. convert the recorded captured movie to wmv/mpg/avi
3. download
www.fakewebcam.com
4. get msn messenger latest version
5. then find some dude/victim to play the movie on
if you want to go further get a screen recorder program to record some dude jerking off and post it to some funny video site it's a laff.
i've watched my wife used this on my work colleagues on the net, its really funny because they didnt know who she was but they were jerking off thinking this fake webcam chick is real.
It's the same technique my friends from the feds use for trapping pedophiles.
