 Dr. Arnn, we were going to break with Dr. Jaffa there, but Sinai in Philadelphia, that has always shocked people even 15 years after I first played it. Yeah, well, he had this amazing elevator. First of all, it's just marvelous to hear his voice. You know, I knew that man for 40 years, more than that. And I just never failed to learn in talking with him, even when he was ordering me about, which he always did.
