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.
YMMV: Shaun the Sheep
Ear Worm: The theme song. It's Shaun the Sheep, it's Shaun the Sheep...
The theme song for the spinoff, Timmy Time, is even worse.
The whistling version that plays at the end of every show might be the ultimate example.
