"Sweet As Pie"

Is, apparently, a very common phrase. That I swear I never heard until a few months ago when Sommer used it, to describe her dentist. Since then, I've heard it approximately 42 times. It makes perfect sense, so I assume it really is a known phrase and not just something tons of people decided to start saying. But... is it? Is "sweet as pie" something you all grew up hearing?

Oh, and as long as we're discussing phraseology, the subject line for the latest Tower Records newsletter made me giggle. "Rock out with your wallet out!" Also, could be interepreted as part of the reason behind the chain's closure.
