Jokes Edit

At 0:11, the rip turns into a mashup of the advertised track and the Cartoon Cartoons theme song, specifically the shortened version of the theme song that was used in the Cartoon Network Studios end card.

The rip also incorporates some of the visuals used in the original end card: the expanding blue rings behind the logo and the subtitle below the logo (the original usually saying "A Time Warner Company", while the subtitle in this rip says "A Toby Fox Company").
