An American returning to the States after a business trip to China is having his breakfast at the Chinese airport. He's having coffee, croissants, bread, butter and jam, when a Chinese man, chewing gum, sits down next to him.
The American ignores the Chinaman who, nevertheless, starts a conversation.
"You American folks eat the whole bread?" American: "Of course we do."
Chinaman: (after blowing a huge bubble) "We don't. In China we only eat what's inside. We collect the crusts place into a recycle container, transform them into croissants and sell them to America."
The Chinaman has a smirk on his face. The American listens in silence.
The Chinaman persists: "Do you eat jelly with the bread?"
American: "Of course."
Chinaman:(cracking his gum between his teeth and chuckling). "We don't.
In China we eat fresh fruit for breakfast, then we put all the peels, seeds, and leftovers in containers, recycle them into jam and sell the jam to America.
The American then asks: Do you have sex in China?"
Chinaman: "Why of course we do", the Chinaman says with a big smirk.
American: "And what do you do with the condoms once you've used them?"
Chinaman: "We throw them away , of course."
American: "We don't . In America , we put them in a container, recycle them, melt them down into chewing gum and sell them to China."
