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: Kids' WB!
Animation Age Ghetto: The promos and bumpers really stressed that this was a kids' block in the first season.
Curtis Williams of The Parent 'Hood: OK, we're back. You grown-ups can leave the room.
Plus, the adult audiences tuning in were a part of the reasons Animaniacs and Freakazoid! were cancelled, even though adults were the only ones that got a lot of their humor.
