This is a parody of a children's song popular with elementary school music teachers called "The Cat Came Back". In that song, the owner of a cat he hates tries to find humorous ways to dispose of the cat (such as tying it to a ship's anchor or sending it off to space), but as the chorus repeats, "But the cat came back the very next day. The cat came back, thought he was a goner. But the cat came back. He just couldn't stay away".
