Trivia
- The Simpsons and Looney Tunes will be reviewed again in Top 6 Cartoons That Got Bad since these two shows became much more bland as these shows went on (The Simpsons: 27 years; Looney Tunes: 87 years). South Park will also be an honorable mention on the same video, when he briefly talks about season 20.
