Seth Snella

Seth Snella is a 2-month year old baby and supporting character in the series. Mr. Snella throws a half-birthday for Seth, and makes the adult guests do crazy things to try and make Seth laugh. He secretly tapes all the parents and sends the videos to "America's Funniest Families". The only time he laughed was when Greg was hanging from a tree with his pants down wearing embarrassing underwear.

Trivia

 * In the Funbrain version, it was Greg falling into a wasp's nest.
