After Fred sets the Christmas tree in the Ricardo's living room, Ricky asks how it looks. Lucy tells Ricky that "there's a branch on the right side that spoils the shape". Ricky asks her which one and she walks up to the tree, grabs the branch with her fingers and, with Ricky and Fred both watching, tells Ricky that's the branch she's talking about and asks Fred to get a saw and cut it off. Fred whips a saw out of his pocket, walks up to the Christmas tree, and proceeds to cut off a totally different branch.
After Little Ricky goes to bed, Ricky calls the Mertzes in with a very soft voice so as not to wake the boy. However for the whole rest of the scene everybody talks and sings rather loudly.
