After just watching Punk'd i remember that something similair happened to me....
I got a phone call from a guy saying that i had his dads wallet.. after exchange of words he was addament that i had it and he wanted it back, apparently the money in it didnt matter he just wanted the wallet back. obviously with this guy going on and on and not listening to me i got a little annoyed...
anyway after about 5 mins of arguing and strong words and me putting the phone down on him several times i got a voice mail message saying that i'd been punk'd
has anything happened to anyone else like this or heard of places or websites where you can set it up. i never found out who set me up or how they did it.
Ive had something similar, in that I got a call from someone saying I had slept with their girlfriend. It was infact a mate who had phoned one of these prank phone lines that you may see sometimes advertised in a newspaper. What happens is when you speak the voice says nothing, then when you dont say anything a pretend voice, in your case the wallet person, has a 'go' at you. Hope this helps
