In an episode when Diana and Martin are spending the weekend camping with their dad, Java has to stay at the Center. He winds up taking on some janitorial duties and is having the time of his life. He's seen happily mopping the bathroom floors while laughing like an idiot and prancing around. What makes this scene really funny is when M.O.M. comes out of one of the stalls, and the completely weirded out look on her face at Java's exuberance.
