I had a buddy call me awhile back wanting to do a joke on his girlfriends sister. Well the sister had put an ad on Craig's list wanting to trade some exotics for a cattle trailer. She had several people call and want to trade things like TVs, and stuff nothing close to a cattle trailer. Well this was makin her kinda upset and with me and my buddy coming up with something to really set her off. He had me message her being she don't have my number or email address. I sent her a message saying I would trade her a very large stockpile of mostly un-used adult toys. Well my buddy and his girlfriend were there when she got the message and said she just went OFF. She tool the ad down and still hasn't got her trailer that she wanted. Really wish I could of seen it but I know that she's still really pissed about it.
This prank sounds a lot like one that they do on one of the local radio stations. I like it.
