Show business is full of vacant teens -- pretty and hollow and shaped by cynical grown-ups. Miley Cyrus and Justin Bieber, however, are not among them.

So it was surprising to see the sketch in tonight's "Saturday Night Live." It was another round of "The Miley Cyrus" show, repeating the false assumption that Cyrus is a no-talent ditz. And guesting was a clueless Bieber (played by the real Miley Cyrus, this week's host).

Crystal Bowersox wasn't exaggerating tonight when she told "American Idol" viewers: "Northwestern Ohio has been in a bit of a slump lately."

A big bit. Ohio, Michigan and Illinois have struggled. So it's a pleasure to see a couple of ordinary kids from the North, fighting for the "American Idol" championship.

Crystal is from little towns near Toledo; Lee DeWyze is from Mount Prospect, near Chicago. They are sort of like the people I meet every day in Michigan ... except, of course, that they have more talent.
