This is too, too funny.
P. Z. Myers of Pharyngula tried to attend a free showing of the intelligent design creationist film Expelled today (a film in which he appears btw) but was apparently recognized by the producers of the film who had security ask him to leave under threat of arrest! The irony of creationists expelling a scientist from a film that claims that ID creationists are treated unfairly by mainstream science is delicious enough but it is hardly the best part. I won’t spoil the punch line, go to Pharyngula and read all about it.
Update: P. Z. has some additional information about what happened in the Expulsion from Expelled incident.
