If you want a joke, you need one.

An American is eating in a restaurant in China. When the waiter brought a panlong shrimp, the American asked, "What do you do with the leftover shrimp shells?"

"of course," the waiter said.

“NO！ NO！ NO！” The American shook his head and said, "In our United States, the leftover shrimp shells are sent to the factory, made into shrimp cakes, and then sold to you in China."

After a while, the waiter brought another plate of fruit. The American pointed to one of the lemons and asked, "What do you do with the leftover lemon peel?" "Of course it was," the waiter said.

“NO！ NO！ NO！”

The American shook his head and said, "In our United States, the leftover lemon peel is sent to the factory to make fruit treasures, and then sold to your China."

When checking out, the American asked the waiter with a smile while chewing gum, "What do you do with the leftover gum?" "Spit it up, of course," the waiter said.

“NO！ NO！ NO！”

The American shook his head and said proudly, "In our United States, the chewed gum is sent to the factory, made into condoms, and then sold to you in China."

The waiter asked impatiently, "Do you know how to deal with used condoms in China?"

"throw it away, of course," said the American humanist.

The waiter shook his head and said, "NO! NO！ NO！ In China, used condoms are sent to factories, made into chewing gum, and then sold to your United States. "
