* BadassDecay: '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? [[spoiler: A house fire that occurred 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 created the Weigel we all know in the series.]] She briefly recovers this in one episode but it doesn't stick.
* CrackPairing: Jones and Garcia. The black Jones and hispanic Garcia are partners when out on patrol, although Garcia is openly racist (he's on a friendly FirstNameBasis with the local Klansmen). In spite of this, the two are halfway competent as partners and have their own RunningGag 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.
* EnsembleDarkhorse: By definition, Terry (Creator/NickSwardson), the [[CampGay flamboyantly-homosexual]] (to the point that even [[ButNotTooGay Dangle]] is a little uncomfortable around him) street prostitute. 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.
* HilariousInHindsight: The episode "Fastest Criminal in Reno" has the cops set out spike strips to take out frequent offender "Fast Eddie" (played by Jeff Foxworthy). Eddie manages to avoid the spikes (by going airborne from a hill), and the cops get into their cars to pursue him.... only to run over their own spike strips. It's funny because, like most other segments on the show, you think no officers would be so stupid to run over their own spike strips while pursuing a suspect, but years later, an episode of ''WorldsDumbest'' presented a video [[RealityIsUnrealistic showing a group of cops doing just that.]]
* HollywoodHomely: 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.
* MagnificentBastard: Usually Dangle, occasionally everyone on the force, but the best example being "Spanish Mike" Alvarez.
* RetroactiveRecognition: 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 DancingWithTheStars.
** Carlos Alazraqui voiced Rocko on the 1990's Nickelodeon cartoon ''WesternAnimation/RockosModernLife''. 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.
** Cedric Yarbrough had a bit part in ''Film/BlackDynamite'' as the [[MeaningfulName aptly named pimp Chocolate Giddy-Up.]]
** Andrew later became the dean at [[Series/{{Community}} Greendale Community College.]]
** The officers once arrest a Japanese suspect and bring in [[Series/{{Heroes}} Hiro Nakamura]] to translate.
* TheScrappy: Declan and Rizzo. Both these characters were introduced right after [[ReplacementScrappy the deaths of Johnson, Garcia, and Kimball]] and served as poor imitations of them. Fans were [[RescuedFromTheScrappyHeap warming up to the latter]], but the show was canned before Rizzo had a chance.
* WhatDoYouMeanItsNotSymbolic: The Police-Tek 2000 "Lazarus" Bicycle Lock.
