Being a punch line is no joke

Ten-year-old Shelby Bloom loves jokes but she is horrified when her mother posts an embarrassing video of her, a video that mean girl Brooke makes sure everyone at school sees. Shelby does not like being the laughingstock, and she does not like being paired with Brooke's best friend, Tessa, on a school health project, but it turns out there are compensations, and soon Shelby has the class laughing with her instead of at her.
