Hey, on other forums I can mess around with people by posting threads such as "weirdest member on the boards (link inside)". Then inside I post a covered up link with text and it goes to the persons profile who clicks on it causing them to think it's them until they realize it's a joke. They think it's a link to someones profile, but in reality it ends up being theirs since they clicked on it. I don't know if this works in php though as many other boards I've done this on were never php. It's a simple prank to mess with people.
