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: Black Hole High
Anvilicious: Since it is a (somewhat) educational show for children, each episode has a very non-subtle moral that is stated by the limelight character during the climax.
Best Known for the Fanservice: "Hemispheres" is a great episode. Not only did the actors do a great job acting the complete opposite of their characters, Corrine got the chance to explore her much-neglected creative side. But what does everyone remember from this episode? Marshall's extremely alluring bad boy alter ego.
