What WAS the punch-line to Uncle Vernon's Japanese golfer joke in Harry Potter and the chamber of secrets?

An American goes to Japan to close a big business deal. The night before, he is very tense so he picks up a hooker in the hotel bar. She speaks no English, but they get their transaction settled and go to his room.

In bed, she is wildly thrashing around screaming out a phrase in Japanese. The man figures she is loving it and tries to remember what she is yelling.

The next day, he is playing golf with his Japanese customer. On the third tee, the Japanese man swings, the ball makes a beautiful arc, hits the green, bounces twice, rolls, and winds up right in the cup -- a hole in one!

Thinking to impress his client, the man repeats the phrase he had heard so much the night before. The Japanese golfer eyes him and says, "What you mean.... wrong hole?

It's in the deleted scenes video from the Chamber of Secrets - the first clip in this video. I don't know what the joke was, but judging by the look on Mr Mason's face it wasn't funny.

You don't know because Dobby ruined the punch line by making alot of noise.
