Weird recorded thing on a Superman cartoon VHS tape!

Here's a very weird VHS recording that was accidentally done on my very old VHS of public domain Superman cartoons (called "Cartoon Classics Vol. 1: Starring Superman") released by New Age Video in 1986. When this happened during the prologue of the first cartoon, a snippet from a Little Mermaid episode suddenly pops up. Maybe I pressed the "Record" button by accident when I was three.
