Just before being sentenced Tuesday to 90 days in jail for violating the terms of her probation, Lindsay Lohan pleaded with the judge, saying, "I'm not taking this as a joke, it's my life and career. I don't want you to think I don't respect you and your terms."

But the perennially troubled star's hand -- actually her fingernail -- told a different story. Written neatly on the middle finger of her left hand was a crass message, one that doesn't exactly show much "respect" for the court or the judge.
