I had fun with a few Internet pranks back in high school; having one friend over at my house, both of us signing onto MSN Messenger on the same computer, and convincing another friend that he'd sent one of us a virus and wrecked our trout. It was easy to play somebody when you were right there together.

One of my good friends in high school/college years was a year younger than the rest of my friends, and was also pretty gullible, so as a result we'd give him endless amounts of trout for the things he'd fall for. We messed with him so much that I actually can't remember any of the lies we'd tell him, just his wide-eyed "Really?" and then the annoyed "Oh Goddammit!" when we owned up to it.
