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.
Jeff and Audrey, due to having taken over the primary couple stuff from Adam and Jennifer.
Fridge Horror: Adam's stupidity might be the result of minor brain-damage, due to the possibility that his Hippie mother continued to take mind-expanding drugs during pregnancy! Considering what we see of her, there is nothing that rules this possibility out!
Hollywood Homely/Pudgy Liz is treated as being hideously ugly and extremely overweight when she is neither.
Also applies slightly when Adam and Jennifer film themselves having sex and are digusted when they watch it. While a lot of their disgust revolves around the awkwardness of their sex, they take the time to remark how awful they look. Adam remarks that he needs to hit the gym and Jennifer shouts, "We are not tan!,"... even though they clearly are.
Ho Yay: In one episode, Timmy and Russel have their hands on each other's knees under the table mistaking each other for their dates.
Adam is fascinated by Jeff's half-naked looks on an old photo, and wants Jeff to find him good-looking on the similar photo he had made of himself. He also asked Jeff to do like he was Audrey.
Russel gets a girlfriend who is Timmy's Distaff Counterpart. At one point, Russel tells Timmy that Indians with British-accents are his "type" and encourages his girlfriend to look more and more like Timmy. Later, he accidentally hits on Timmy.
On the other hand, some fans actually consider Russell this (although his recent character development has begun to lessen this), with Timmy's passive-aggressive snarking at how utterly inept Russell to be both deeply refreshing and making him something of an Ensemble Darkhorse.
