Parodying a high school principal? Weak but understandable. Making a MySpace profile for him which reads "I like to give anal to the little boys at my school"? Less defensible and possibly libelous! But after a thirteen-year-old boy was expelled from school for making the profile (which also lists Hitler, Michael Jackson and a purple strap-on as the principal's heroes), his parents are suing the school for violating the boy's free speech rights, since he made the joke on his own computer and because it's so clearly not a serious accusation of child rape. Below is the now-deleted profile, or at least the terribly grubby copy used in the court filing. If anyone has a better screencap, send it to firstname.lastname@example.org.
The more I think about it, the more it sounds like the kid has a case, even if he's a nasty (and uninspired) little demon.
