I missed the show myself, but there was an ad put in K-Scene here in Seoul as a joke that sparked lots of discussion and apparently got a mention on Leno. Here is some info:
Canadians banned from group for cultural understanding
"An organization that promotes cultural understanding and brings together people from different nations is open for anyone in Seoul to join. Anyone that is, except Canadians.
In a classified ad in KScene, a free biweekly magazine, World Class describes itself as a group that "brings together all nationalities to discuss world issues and break down cultural barriers and prejudices."
Breaking down the prejudices, however, doesn't extend to all countries. "No Canadians please," the ad continues.
When contacted by a Korea Herald reporter by e-mail, the organizer of the group, Bernard Carleton, elaborated further, "The thing is, CANADIANS ARE SCUM! They are self-loving, welfare supporting, over taxing, work ethic hating scum!!! They are not welcome in our group."
Anyone who would like to join the meetings with Carleton in order to break down prejudices, dissolve stereotypes and have an enhanced understanding of people from other countries can contact him at email@example.com. "
