Query: So bad it makes my head hurt

This guy Groban is a corny kook. He sings sappy, awful love songs. The fact that so many people like him shows how stupid so many people are. When I see him on TV looking all mopey and dopey, I want to punch him in the face. If you like horrible junk like Celine Dion and Clay Aiken, you'll probably like Josh Groban too.
