That's a great cartoon. Wish I'd had it 37 years ago, when Canada converted to metric. I was working on ranches then, and I nearly started a riot in a bar in Kamloops, talking to a bunch of cowboys and ranchers, all of whom thought thAt the whole idea of the metric system was some sort of left-liberal-loony conspiracy (gosh, seems I'ver heard the same reaction to climate change - must be just a coincidence). I kind of egged the discussion on - one does enjoy a good loud bar argument every now and then.
When it slowed down a bit I revealed (lied, actually, but I pretended to reveal) that converting pounds to kilograms and miles to kilometers was just the beginning - once we were used to it, the government was going to go to a 10-hour day and 10-day weeks. The sh*t hit the fan, guys were so pissed off that they were yelling at each other, the beer orders went up, everyone in the bar got involved, and it was just a hell of a good time all around. Almost makes me wish that we could have similar meaningless arguments now.
