There was this group a few years back that I'm sure was created so MuchMusic and Canadian radio stations could fill their CanCon quota called 'ID' (for 'Identically Different', I think). Now, if their song wasn't bad enough (about their girlfriend cheating on them, 'You've been busted/And you can't be trusted'), the video had this lame dance scene with them in an alley with nunchucks.
Oh, and I can't forget the Canadian PopStars Sugar Jones. Their songs sucked but their videos were so hilariously bad that you had to watch them. I always crack up at the end of the one where they're all in a circle singing to each other about when days were like that. So fucking bad.
