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.
Dude, Not Funny!: One episode talks about Benny's mother, George's grandmother, where Benny was punished by the nuns in school by being hit with a ruler, then beaten with a switch by her mother. If that was not bad enough, he then says Benny's father came home and beat his wife because dinner was not ready. Meanwhile, the laugh track continues playing in the background like a story of child and spousal abuse was absolutely hilarious.
It becomes genuinely funny when George says that Benny's father was eventually beat by "tequila and a curve in the freeway."
Family-Unfriendly Aesop: The show gives the moral that sometimes bullying can get so bad, you have to run away from the situation. Carmen was called a whore at her first high school, due to her ex-boyfriend telling everyone that they had sex. George and Angie get the leader of the bullies suspended, and get the ex-boyfriend to tell the truth. However, the episode ends with Carmen still getting bullied, and George and Angie making the conclusion that Carmen can never get her reputation back, and that she must leave the school. Unfortunately, all of this is Truth in Television.
Fridge Brilliance: Danny boy, a lazy worker voiced by Lopez, always called into work with hilarious phone calls, making excuses for not being there. This eventually stops, and seems like Chuck Cunningham Syndrome, but considering he never showed up, he was actually probably fired.
"Funny Aneurysm" Moment: An episode in the final season involves Geroge being in the local neighborhood watch. While their goal is a little different (it involves finding a child molester who ends up being a woman) it is a little jarring considering the George Zimmerman incident. (A hispanic man named George who was also involved in neighborhood watch)
Growing the Beard: The first season was rather forgettable, being little different then most family sitcoms with generic storylines and not-so-great humor. The second season, however, featured the inclusion of many story arcs, and a much more mature and better-received sense of humor.
Harsher in Hindsight: In one episode, George says that he's in favor of tighter border control, and now look what's happening with Arizona, be careful what you ask for!
Ricky was Max's delinquent friend who talked Max into a lot of stunts that damaged the Lopez house and drained their finances. But his childhood was pretty much the same as George's, maybe even worse, so George was willing to take him in.
Veronica was a spoiled brat who tested George's patience more than once. But his father was a manipulative conman who abandoned her, and returned again just to steal her trust fund money. Her mother was apparently dying for a while, and it's implied that her relatives were also poor role models for her, since her mother Claudia made George a trustee, and one of them later sued Veronica for her money, forcing her to live with the Lopez family.
Zack Powers is a subversion. He may have had a difficult childhood, but his embezzlement of company money, trashing the factory just to spite his father, and then trying to manipulate Carmen into having sex with him, and then running away to San Francisco completely shreds any sympathy.
Les Yay: In one episode, Veronica mentions that she was hit on by two store managers.... and that one of them was a girl. Max, who was with her at the time, comments, "It was awesome."
Uncanny Valley: The flashbacks to George's childhood, which show George's adult head pasted on his childhood body. Extreme Narm ensues when said scenes are intended to be serious, such as the flashbacks that led up to George's abandonment or Bennie's neglectful parenting. Needless to say, these scenes can't be taken seriously with the adult head/child body combo.
Rewatch Bonus: In the episodes leading up to "George Helps Ernie See The Cellulight" where Ernie gains weight and almost gets fired, he is noticeably heavier. George even comments on it in the episode "The Kidney Stays in the Picture."
During Benny's trial, George brought in Benny's mother to the stand and try and make Benny sympathetic to the jurors. While on the stand, she proceed to mock Benny and shows how bad a mother she was to Benny. This was done to make Benny seem like a Jerkass Woobie at the most since how bad she grew up in a broken home and being a single mother. The problem was that Benny was just as bad at raising George. Being emotional and physically abusive to him, being neglectful of his feeling, disregarding his learning disability, unsupportive of his goals, and lying to him constantly. And as an adult she still a Jerkass to him and his family. It pretty hard to sympathize with her.
Benny falls into this a lot. In one episode, George completely remodels her bathroom, free of charge (and even throws in some custom stuff). When she complains about this and he rightfully calls her out for being ungrateful, she launches into a rant about all the bad things that happened in her life. The logic gap from being angry at people in your past and never saying thank you to your son is pretty blatant.
Vindicated by Cable: A modest hit on ABC, it has found tremendous success in syndication, especially on Nick at Nite, where it draws the highest ratings on the channel's late-night block.
The Woobie: Carmen hasn't had it very easy. George has often shown more favor to Max. Her best friend left her, one of her ex-boyfriends called her a whore, resulting her in being bullied so bad she was pulled out of school. One of her boyfriend's was a lying slimeball who just wanted to screw her, and manipulated her into running away to San Francisco, and later dumped her. Her next boyfriend was at first embarrassed with her, and then cheated on her. The girl has been through a lot, and you hope she can achieve more in college.
