Diane from If I Fall, If I Die remembers watching The 400 Blows with her ex-husband Arthur and thinking that a shot of rapt children was the most beautiful image she'd ever seen in a film. She thinks that was what made her decide to have a child.
A "Monsterpiece Theater" sketch from Sesame Street is entitled "The 400 Blows". In this sketch, Grover tries unsuccessfully to blow out the candles on his birthday cake. The other monsters count how many times he tries, but only get to 40 before Grover runs out of breath.
