The Cold War

Kel has a bad case of the flu. Kenan tries to cure him with a homemade remedy consisting of just about everything in the kitchen. To their surprise, Kel is in perfect health the next morning, which gives Kenan an idea. In their quest to reformulate their cure for the common cold, more than a few ingredients are mistaken and they end up with a cure with an uncontrollable side effect: deep sleep. All is well until the boys realize they have given the cold medicine to Kenan's father--an air traffic controller.
