Remind me of a time I was in Germany. I was out with some friends (none of us was german) and one friend joked about hitler, he put a finger over his mustache and did the hitler salute to tell a joke. A guy who was standing next to us came running and said you will get jailed if the police who were close to us see you. So much for freedom to tell a joke.
It seems this is the norm, so be careful when in Germany [1].
