I don't know about other cities, but for Nuernberg/Fuerth the definite sign for being home is entering the metro and the driver saying "Pleahz schteb bek" (trying to mimik franconian accent in English isn't really easy :) as the train leaves the stations. I know several people (including my mother) that insist on taking the metro if they are around just for that to happen. And just today I was in a train where the driver tried to speak plain german, but then again in the tone of a city guide. Very nice touch for those getting up early actually :)
I just missed to hear about the weather conditions at Lorenzkirche, that would have polished it all. I will really miss this daily comedy show when they switch to all automatic trains (still some time ahead though).
How about this one, Miss Varcuzzo?
