Originally there were two versions of SCTV - the US version and the Canadian version. The Canadian version had two extra minutes because it had less commercial content. The Canadian Broadcasting Corporation specifically requested that these two minutes of extra air time be filled with 'Canadian Content' material.

So as a spoof to the request for 'Canadian Content' material, Dave Thomas and Rick Moranis created two outrageous, beer guzzling ultra Canadians.They took all things stereotypically Canadian, intensified them, and rolled them into two characters - Bob and Doug McKenzie.

Now pass me some back bacon, you hoser!
