This is quite simple and is great at getting back at someone. Just go on ebay and list an auction selling an embarassing picture of your friend or whoever you want to get back at... Write a funny description and title. ie: "1 Picture Of Jimmy Smith Drunk in a Bikini, Great Gift!" Start the bidding at 1 cent. Most likely you wont get any bids, but if you do, just make sure you have a copy of the picture ready to send to whomever actually wanted it! Once it's up, then tell your friend to look up their name on ebay and watch their reaction when they see their face being sold. This is a great laugh!
