Wilting in the heat as he tries to play tennis, Harry loses repeatedly to his obnoxious cousin Harley. After Harry realizes that Harley is keeping himself cool using water from a spray bottle with a fan attached, Harry decides to up his game. With a large sprinkler hose and three window fans, he harnesses the power of evaporative cooling on his side of the court, and defeats Harley without breaking a sweat.
