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: Reno 911!
Badass Decay: 'VHS Transfer Memory Lane' reveals amongst other things that Weigel was not only once confident and competent as a police officer, but also smart and even had Dangle of all people attracted to her. So, what happened? A house fire that occured while the team was on the scene caused a chain reaction and started/created the Reno officers we know today. In Trudy's case, she was clinically dead for 2 minutes but came back and the damage to her brain from the smoke inhalation damaged her brain and created the Weigel we all know in the series. She briefly recovers this in one episode but it doesn't stick.
Crack Pairing: Jones and Garcia. The African American Jones and Latin American Garcia are partners when out on patrol, although Garcia is depicted as racist. In spite of this, the two are halfway competent as partners and have their own Running Gag of extended chase scenes throughout the show.
Weigel and Williams. Despite Weigel also being racist (though she blames the racial tension on the squad on Garcia), Williams is probably her closest friend at work. The season 6 finale even has them posing as a lesbian couple.
Ensemble Darkhorse: By definition, Terry. The character appeared in 27 episodes (out of a total 88), and was easily the most popular recurring character not in the main cast. He even got screen time in the movie.
Hollywood Homely: Deputy Trudy Weigel. She's supposed to be extremely repulsive. The stings involving her playing a prostitute or a stripper never work.
Garcia: "She's a 'triple-bagger'. One bag over her head, one over mine, and one extra for any unlucky bastard that might accidentally walk by."
Magnificent Bastard: Usually Dangle, occasionally everyone on the force, but the best example being "Spanish Mike" Alvarez.
Retroactive Recognition: Subverted with Niecy Nash, who hosted the Style Network's "Clean House" for seven seasons; she was the only one to have a steady gig simultaneously with Reno 911!. Her hosting outlasted her role on "Reno" by one season. She also spent a season on Dancing with the Stars.
Carlos Alazraqui voiced Rocko on the 1990's Nickelodeon cartoon Rocko's Modern Life. Of course, the two roles are completely different.
Wendi McLendon-Covey had a major supporting role in "Bridesmaids".
Nick Swardson went on to have mainstream success as a comedian and a film actor, an interesting note since he was not in the main cast.
Just as often inverted, subverted, or averted, though: for example, it's hard to name another show where a character is openly homosexual, in a role of some authority, and has an active sex life. OK, he's a total idiot, but he's still the smartest guy in the station, and not even the rednecks like Junior or Garcia have a problem with his personal life.
