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.
Family-Unfriendly Aesop: In an episode, Diana reads Martin's private diary and discovers the negative things he thinks about her, Java and Billy. She reveals this to the latter two and they punish Martin by the end of the episode! As if reading someone's private diary justified it...
Ho Yay: In one episode Martin and Java share a sleazy out of the way motel room together, sleeping in the same bed, both only wearing their underwear.
How about Clifford from the Christmas Episode? He was perfectly willing to kill Martin and Diana, plus two innocent motorists who accidentally got stuck in the snow globe world, by baking them into fruitcakes in order to preserve his "perfect Christmas". Also some of the creepy faces he pulls.
