Eleven-year-old David Greenberg dreams of becoming a TV superstar like his idol, Jon Stewart. But in real life, David is just another kid terrified of starting his first year at Harman Middle School. With a wacky sense of humor and hilarious Top 6½ Lists, David spends his free time making TalkTime videos, which he posts on YouTube.
But when David and his best friend have a fight, David is lucky enough to make a pretty cool new friend, Sophie—who just (gulp) happens to be a girl. Sophie thinks David's videos are hilarious, and she starts sending out the links to everyone she knows. Sophie's friends tell their friends, and before David knows it, thousands of people are viewing his videos—including some of the last people he would have expected.
