By the Beautiful Sea 93 years old

A boy dog walks down the train tracks singing "I Ain't Got Nobody," with a train coming. He looks at a photo of his girlfriend, and she razzes him. He lies down on the tracks, but the train bypasses the section of tracks that he's lying on! He jumps off a cliff, but a tree saves him. The ball bounces... we see him on the sidewalk, crying, and singing to passersby.
