The ending of "Dangerous Lumber" is a callback to the ending of the season one episode "The Baseball." In that episode, Arnold returns Mickey's home run ball and they play catch as Mickey tells Arnold about his time in the World Series. In "Dangerous Lumber," Mickey returns Arnold's home run ball and they play catch as Arnold tells him about his winning bat. Even the dialogue is almost exactly the same.
