Shelby Bloom is the new kid at school, and she's in search of an identity. Taking stock of herself, she worries that she's no sports superstar, no wiz kid, no social butterfly and no beauty queen. But she is funny at least she thinks she is (and her sister says she's a riot). Shelby decides she'll be the funny girl, the one who wins friends by keeping them in stitches. Soon she finds that while she really does have a comic flair, she also has a few things to learn about what makes people laugh, when the timing is right and how things can go wrong for the jokester.
