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.
Ho Yay: In the episode where Gary ends up accidentally splitting himself/cloning himself. The final Gary, "Good Gary", is gay, and starts to hit on Ron. If these are parts of Gary, you have to wonder what this implies about him.
Tear Jerker: The old and senile Reg Dedman and to a lesser extent the expression on Gary's face when he meets his grown up alcoholic son Michael in the 1990's and realizes that he had failed as a father by never being there for him.
