1x23 - The Pink Panther

The Pink Panther decides to be a superhero, and tries unsuccessfully several times to help an elderly woman in various ways. After failing to save her from an oncoming train, the fed-up elderly woman enters a phone booth, and comes out, revealing herself as a superhero as well; she pulls out a nearby railroad signal from the ground, and chases the Pink Panther into the horizon, attempting to whack him with it.
