Thomas was talking about how he's been well-received at law schools around the country. But, he added, there are some elite law schools from which he does not expect an invitation. "About the only way I would get invited to Columbia is if I was a Middle East dictator with nuclear weapons."
Yesterday, I linked to a joke Justice Thomas made about not being invited to speak at Columbia unless he was a Middle East dictator with nuclear weapons. Keeping in mind that this was a joke and assumedly was not meant to be taken literally, it's still worth noting in fairness that informed sources tell me that Thomas has in fact been invited to speak at Columbia Law School, and has turned down the invitation. Moreover, Columbia Dean Schizer has made it clear (speaking for himself) that he thinks inviting Ahmedinejad was a bad idea. So, while the nub of Thomas's joke was that someone like Ahmedinejad may be more welcome in certain elite educational circles than he is, that's not true of Columbia Law School.
