"I started the Restroom Association of Singapore in 1998 to clean up public toilets. Then I started the World Toilet Organization. I went to a very experienced person who is doing something like this [for condoms] in Thailand, “Mr. Condom.” I said, “How do you do this?” He said, “Can you make people laugh?… If you make them laugh, then they’ll listen to you.” So I created the acronym WTO, playing a pun on the World Trade Organization. The media loved it."
