we melt them down into chewing gum and sell them to the United States

A Canadian man was in a diner having coffee and croissants with butter and jam when an American man chewing gum sat down next to him.

The American snapped his gum and said, "You Canadian folk eat the whole bread?"
The Canadian replied, "Of course."
The American blew a huge bubble. "We don't. In the States we only eat what's inside. The crusts we collect in a container,recycle them,transform them into croissants and sell them to Canada."

The American had a smirk on his face. "D'ya eat jelly with the bread?"
The Canadian replied, "Of course."
The American cracked his gum between his teeth. "We don't. In the States we eat fresh fruit for breakfast. We put all the peels,seeds and leftovers into a container, recycle and transform them into jam and sell it to Canada."

The Canadian asked, "Do you have sex in the States?"
The American replied, "Of course we do."
The Canadian asked, "And what do you do with the condoms once you've used them?"

The American replied, "We throw them away of course."
Then the Canadian smiled. "We don't. In Canada we put them in a container, recycle them, melt them down into chewing gum and sell them to the United States."
