Hey, I just realized something! In comments here and here, readers were talking about "ParticipAction", Canada's physical fitness promotion from the 1970s. Someone mentioned Hal Johnson and Joanne McLeod, and I asked who they were.
I just realized that I see these two wankers all the time. Since I've been working full-time, before I go to sleep - too tired to read or even watch "The National" - I've been watching "Seinfeld" reruns. Before the show, there's a cheesey public-service ad for "Bodybreak", and last night I actually listened to their introduction: "Hi, Hal Johnson and Joanne McLeod here..."
They were someone's pick for Most Annoying Canadian, and although I would still vote for Canadian Tire Guy, these two are definitely in the running.
