These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.

Awesome Music: The theme song. Even more awesome: the instrumental version that plays during the end credits.
Ear Worm: The theme song, as well as a lot of the other songs they sing.
