A few weeks ago I wrote a story about how Boston can't quit cupcakes, despite the fact that the rest of the country put that trend to bed years ago. So, for those who can't get enough cupcake action in there lives, here's cupcake toothpaste. Strangely, it doesn't say which flavor of cupcake you're brushing with. Which one of you readers is going to try this and tell me? OK, twist my arm. I'm ordering now.
