Japanese Prime Minister's English skills

This is a true story from the Japanese Embassy in US!!!

A few years ago, Japanese Prime Minister Mori was given some basic English conversation training before he visits Washington and meets President Bill Clinton...

The instructor told Mori, the Japanese Premier, when you shake hand with President Clinton, please say 'how are you'
Then Mr. Clinton should say, 'I am fine, and you?'
Now, you should say 'me too'. Afterwards we, translators, will do the work for you.'

It looks quite simple, but the truth is...

When Mori met Clinton , he mistakenly said
'Who are you?' (instead of 'How are you'?'. )

Mr. Clinton was a bit shocked but still managed to react with humor:
'Well, I'm Hillary's husband, ha-ha...'

Then Mori replied
'me too, ha-ha.. .'.

Then there was a long silence in the meeting room. _,___
