I have a friend that drove taxi and regularly picked up Joe Ratzinger (before he became Benedict) for trips from Regensburg to Munich.. they used to discuss all kinds of things... on one trip the subject came around to monotheism versus polytheism. My buddy believes in many of the old Germanic dieties, so they didn't see eye to eye on this... The conversation got heated and the Ratz was ordered out of the cab. He was left standing by the side of the road out in the country. So I guess I can say I know someone that threw the Pope out of a taxi..
Joe made out okay, and has some fancy digs in Italy now....and probably will never have to hitchhike again...
