Eh?

I am the only one who misses the word eh? It seems to me that no other country in the world really grasps the whole eh thing. I dunno, I just really really like saying eh-that an singing that "Ex says it all" song from like 1992 just to REALLY annoy people

The following is a passage from How to be a Canadian by Will and Ian Ferguson..

Eh? is what separates Canadians from the unwashed, envious hordes outside their national boundaries. (You know who you are.) Eh? is the secret password, the cross-Canada countersign, a two-letter, single-syllable symphony that takes years of diligent study to master. It must flow naturally into the sentence. It must never stand out, never call attention to itself –and yet must remain inextricably linked to the harmonial whole. It should trip melodiously off the tongue. “Howzit goin’, eh?”

OMG, I know eh!

i make more use of 'HEY! ...' than 'EH?'
and my all-time favorite is 'HUH?'
