There really is a website called "Conservatives For Palin" and they really, really do have a banner with a misspelled word on it.
And I realize that this is absurd and could be entirely wrong, but the phrase stamped on the old Scottish coins was "Nemo Me Impune Lacessit," which is roughly translated as "no one cuts me with inpunity."
The Palin site spells the word as "lacesset." This is an obscure spelling on the Internet. It is vastly more common to spell it "lacessit."
What? I'm bored.
