I read an amusing story once, not sure how true it is though. A businessman had to meet with a group of Japanese investors and figured if he could learn some Japanese he would impress them so he took some lessons. He found a teacher, a woman, and did very well and was able to communicate somewhat and was ready for the meeting. When he got up and introduced himself in Japanese they all broke out laughing. Not because they could not understand him or he got the words wrong or made funny sentences but because he spoke like a woman.
Probably not true but funny all the same.
