I served on a jury shortly after graduating college. It was fine, because I didn't have a job at that point and didn't have anything better to do.
However, if you were to ask me today to serve on a jury I would do whatever I could to get out of it. I have too many other things on my plate to worry about small stuff, like the pursuit of justice. I could simply say that I don't think I can be impartial and that normally gets you off pretty quickly. But that seems boring so I think I'll use one of these more creative responses.
