This all starts on Jahsonic blog in an entry on National stereotypes from 2006. Well, I guess it goes back to the 1970's, but we will get to that in a minute. This led to a follow-up post in November 2006, quoting:
Heaven is where the police are British, the cooks are French, the mechanics German, the lovers Italian and it's all organised by the Swiss.
Hell is where the chefs are British, the mechanics French, the lover's Swiss, the police German and it's all organised by the Italians.
I believe I originally saw this in the 1980's. The interesting thing about this post is that the quote is attributed to Ahmet Ertegun. Ertegun was a pivotal figure in the early days of rock music, signing Led Zeppelin to Atlantic Records and convincing CS&N to add the Y. He was a founder of the Rock & Roll Hall of Fame and was inducted in 1987. Upon his death, the surviving members of Led Zeppelin performed their last concert together.
