Why Ten Bucks is Ten Bucks, eh?

Oftentimes people pepper their speech with jargon that nobody else understands. I know this to be true in the rock world. For instance, when I say jokingly to people in a Canadian accent "Ten bucks is ten bucks, eh?" I often get blank looks. What IS she talking about? That particular saying relates to an instance in time when Geddy Lee, the bassist/vocalist for the band Rush recorded with Bob and Doug McKenzie, a fellow Canadian act, albeit a comedy act. He sang the chorus in their tune "Take Off." Very funny stuff, the video is here:

"Thanks for coming down to do our hit."

"Well, it's my pleasure, eh."

"Did, did our lawyer call you?"

"Yeah, um, I, you know, ten bucks is ten bucks."

Now don't you feel smug knowing what that means?
