Did you ever get mail and wonder “How did this company get my address?”. Well with a little help, you can help you victim to junk mail insanity. All you have to do is go through all the newspapers and magazines you can find, and send for free information, using your victims name and address. The more you can find the better, and certainly the more obscure the better.
A word of warning though, when I played this joke on my sister, a salesman turned up on her doorstep after driving 80kms, to talk about the “information” she had (not) asked for. He wasn’t impressed when she had no idea what he was going on about. I thought it was quite funny though.
