P.Z. Myers and Richard Dawkins went to see a screening of Expelled! (Both were interviewed in segments for the movie.) Myers was identified as persona non grata and asked by a security guard to leave the premises. Dawkins got in and saw the movie, albeit with a security guard watching him every time he appeared on screen.
Epic failure of irony meters everywhere ensued.
