I took a random tricycle bike tour of Saigon or Ho Chi Minh City at one time. At one street, I saw the strangest sight. I asked my cyclo (trishaw) driver who are all these people sitting by the roadside, all with a single, shiny VCD disc at their feet?
Selling "Human Reproduction Videos", he explained, perhaps embarrassed.
I told him we buy human reproduction videos at night markets back home. They have catalogs. Also we are more practical, we just call them blue or sum kap, I mumbled to myself, not sure if he can hear me through the traffic din.
