Poor Grover...Big Bird was looking into the camera and showing the TV audience about the number 2. Grover is hanging from a wooden bar up on the staircase and demonstrates the number 2 by doing 2 chin-ups. Despite pleas from Grover to finish the demonstration, Big Bird insists on Grover repeating the show 2 or 3 more times. Finally, BB believes that everyone now knows all about the number 2 and now tells the TV audience, "Grover will demonstrate the number 18"!!! Grover faints and is seen laying on his back with the staircase collapsed on top of him.
