The baby woodpecker wants to save Jerry from Tom. He uses trigonometry to find the right angle at which to cut the telephone pole in order to hit only Tom. While the math equations are not correct, the premise of the woodpecker's math is correct.
Carter speaks with Peter about a stunt he pulled involving music. He tells Peter that music is forbidden in prison, and Peter calls him obtuse. Carter creates an obtuse angle using his body and creates an acute angle soon after to show that he isn't obtuse.
