An American business man takes a trip to China and while he's there he decides to pick up a hooker. While they're having sex she begins to scream, "Lay-na! Lay-na". Since it's so loud the American assumes it's a sign that she's really enjoying the sex so he screams back "YES! YES!" The next day he's golfing with some Chinese business associates. He shoots a hole-in-one and starts jumping around screaming "Lay-na! Lay-na!". Puzzled, the Chinese guy asks, "Why are you screaming wrong hole?"
