Two guys are playing golf -- a Japanese and American. The Japanese man, getting ready to tee off, begins talking into his thumb.
The American says, 'What are you doing?'
The Japanese man says: 'Oh, don't worry. With microtechnology, I have a microphone inserted in my thumb. I was just recording a message.'
The two men go on playing golf. All of a sudden, the American man makes a funny sound that sounds amazingly like a fart.
The Japanese man looks over at him.
'Oh,' says the American. 'Don't worry, I'm just receiving a fax.'
