* EarWorm: The theme song.
* ViewerGenderConfusion: What-a-Mess's voice is not extremely indicative of either gender, and since he's not a FunnyAnimal, he lacks any TertiarySexualCharacteristics as well. On top of that, the natural traits of Afghan Hounds tend to make them look rather [[http://en.wikipedia.org/wiki/Afghan_Hound feminine by default]]. When What-a-Mess is clean and groomed (a rare occurrence) one could easily be forgiven for mistaking him as a girl.
* TheWoobie: Whatamess himself in quite a few episodes.
