I did a year in Iceland a back in 1995-96--The guys there had a program for acclimating you to the new timezone. Get off the rotator, sleep until dusk, Go to Rekjavik and get positively plowed. In theory, you wake up exactly on Icelandic time a day later...
Going home from the bars in Rekjavik, I found the need to releive myself and I asked the other guys where the mens room was. They said "take a leak on that green building. Everyone does." and there were 3 other people doing it, so I figured it was okay. Halfway through, I saw my sillouette appear in the spotlight of a policeman...I was thinking "Man, these are NOT the right circumstances to meet my new Wing Commander..." I turned around to apologise and the cops said "Its okay--everyone does it..." I still laugh at that.
