This one of the first seasons episodes and it one of the series classic episodes.
Ned finds his teacher McSweeny hard and devises a plan to be nice to him and get a good grade. Moze class has a subsititute teacher and is upset when it disrupts the class. Cookie has puppy love for his hot Spanish teacher and is getting bad grades. Ine the end, Ned learns to study and earn his grade, Moze helps the sub teacher gain respect, and Cookie switches class to avoid failing.
Another series classic. Cookie has made an paper airplane that flies outta control and is given dentention. As Moze and Ned defend Cookie, they also are given detention. Ned, Cookie, and Moze realize they will be serving detention with 8th graders. Moze, however ends up cleaning erasers. Cookie in his gangsta outfit(worn for a 2nd time) and Ned tries to act tough but it doesn't work. Luckily, McSweeny is monitoring detention and is fooled into tricking the bullies, unknowingly, helping Ned and Cookie escape.
BTW, we are shown throughout the ep, the paper airplane flying around and creating havoc in the hallways!
These are series classic mini-eps and they are very good!
