For me it's Corner Gas. I still think it's pretty funny and there's a decent amount of references to Canadian stuff but not enough to be off-putting. I feel like an American wouldn't be confused watching it even if some of the references get a bit dated overtime.
I have only seen a bit of the animated version in waiting rooms.
Along with SCTV, Bizarre and Kid in the Hall were god damned hilarious! They were like a maple flavoured Monty Python.
I forgot about Bizarre. God I miss Super Dave.
