Something is wrong with the Chief Justice's brain.

Linda Greenhouse writes:

Chief Justice John G. Roberts Jr. was hospitalized on today after suffering a seizure at his summer home in Maine, the Supreme Court announced.

The episode, described as a “benign idiopathic seizure,” was similar to one he suffered 14 years ago, according to the court’s press release. Idiopathic means that the cause of the seizure remains unknown....

“In the majority of seizures you see no anatomical cause,” [said Dr. Langer, who is also an assistant professor at Albert Einstein Medical College,] said. A cause could be a tumor, bleeding in the brain, a clogged blood vessel or an injury.

ADDED: From the Maine newspaper:

St. George Ambulance responded to a call at about 2 p.m. Monday of a man who had fallen 5 to 10 feet and landed on a dock, hitting the back of his head. The patient was ashen and was foaming at the mouth.

ADDED: This is the sort of thing that makes me glad I cut Wonkette from my blogroll a few weeks ago.

UPDATE: He looks okay now, doesn't he?
