When I first read this story earlier this afternoon, I thought it was a joke. I read it in Wired which isn't Onion-like in its reporting, outside of April 1. So I checked into it and learned this is in fact true.
California Governor Arnold Schwarzenegger wrote a veto message regarding a bill from Assemblymember Tom Ammiano. The first letters of sequential lines in the left-hand margin spelled out the words "Fuck You".
Here's the letter.
Ammiano had strongly criticized the governor in early October and reportedly told Schwarzenegger at the time to “kiss my gay ass.”
One good turn deserves another. Well played, Governator.
