The Catholic League has responded to South Park's response to the Catholic League's response to South Park, you'll be glad to know.
It would appear that the April 4 episode, "Fantastic Easter Special," was a parody of The Da Vinci Code, with League president Bill Donohue cast as the dark, powerful villain who must protect the secret of Easter at all costs. Wikipedia's article has this to say:
"William Donohue is parodied as a ruthless executioner leading a band of ninjas. Donohue has been a vocal critic of Trey Parker and Matt Stone's work in the past, in particular but not limited to the South Park episode "Bloody Mary." Bill Donohue's character in the episode calls Kyle, Stan, and Randy "whores," which is a reference to Donohue's real-life labelling of Trey Parker and Matt Stone as "little whores."
...all of which is a lot more interesting than anything Rosie O'Donnell has done lately.
In the press release we got this morning, Donohue says "I stand convicted and have no defense. Now I have to get back to business - I hear someone just took some liberties with the Easter Bunny."
No, really. He said that. Click it and see.
