A Sri Lankan is calmly having his breakfast when an American, typically chewing gum, sits down beside him. The Sri Lankan ignores the American who begins to chat:

The American : Do you eat that bread-entirely?
The Sri Lankan : Of course!
The American : We do not. We only eat the inner part, the crust is put in a container, later processed, transformed into flour and then sold to Sri Lanka. The Sri Lankan says nothing.

The American continues : Do you eat this jelly with the bread?
The Sri Lankan repeats : Of course.
The American : We do not. We eat our fresh fruits for breakfast; we keep all the peels and seeds in the containers. Later we process it, and transform it into jelly and then we sell it to Sri Lanka.

The Sri Lankan asks : And what do you do with the condoms after you use them?
The American : We throw them away, of course!
The Sri Lankan : We do not. We keep them in containers, process them, transform them in to chewing gum and then sell it to the United States.
