I worked for a company who interviewed someone who turned out to be a habitual scammer. He somehow managed to know enough technical information to get past a phone screen, and in the in-person interview claimed to be the second coming of Christ. When he didn't get hired, he sued for religious discrimination. Fortunately, all communications with and about him were entirely professional and didn't include a reference to his claim, so (iirc) the case was tossed in short order. That being said, you don't need to do anything to get sued- you just need to have something worth suing for.
