Bubble gum
 

A Canadian was in France, out of his wallet he removed a stick of gum he had from the airport in Canada, and started to chew it. He walked into a French coffee shop and sat himself beside an English speaking French man.
Frenchman: In Canada, what do you do with your used tires?
Canadian: We send em to France to get turned into paper plates.
French man: What do you do with your used plastic bags?
Canadian: (after blowing a huge bubble) We send em to France to get turned into a gold ring. Hey, what do you do with your used condoms?
French man: we send em to Canada to get turned into bubble gum.
