6teen - Season 1 - Eps 23: One Quiet Day
The gang is in agreement - Jen is always butting into everyone else's business. In fact, they’re convinced that it is physically impossible for Jen to keep her opinions to herself for 24 hours. Jen, being competitive in nature, decides to take that bet. The gang have some fun toying with Jen and come up with wild plans that they know that she knows are a bad idea in order to win the be. Meanwhile, Jude’s been acting strangely lately, skipping skating sessions, forgetting about movie marathons with the guys, losing passion for his Stick-it art - it's very anti-Jude. After much sneaking around and spying on him (Jen tries to resist but gives up and takes a loss on the bet - this is way too interesting!), the gang learn that Jude's ""big deep dark secret"" is that he’s flunking several classes at school. They all get together to help him get his grades up... but will Jude have to repeat a year?
