Overview: Volunteer fire chief Uncle Joe has designed a new nighttime alarm system. When a valley resident sets off a skyrocket in the event of a fire, a volunteer will fire off a cannon. But there soon is opposition to Joe's plan because, even though the canon fires blanks, things still get damaged. A fire breaks out on the Cannonball. Because Joe has all the fire equipment at the Shady Rest, Sam has to call the Crabwell Corners Volunteer Fire Department. Joe challenges Bink Sharfells, Crabwell Corners Fire Chief, to see which volunteer fire department is the best. When none of Hooterville's firefighters want to accept the challenge, it looks like Joe will lose by default. Kate and the girls offer to help. The contest winds up a tie. Joe suggests a game of checkers to break the tie. Bink loses the game to Dog.
