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.
Anvilicious: Everybody knows that friendship is very important, but in a few occasions it gets quite exaggerated.
Big Lipped Alligator Moment: In "Honor Thy Father" a Very Special Episode of the second season, Latka tangles in two occasions with a Puerto Rican man (who wasn't mentioned afterwards) who spends the rest of his screentime singing "El Jibarito". It's hard to know if he was intended to be an interim between John Burns and Jim Ignatowski note Iggy didn't become a regular until "Alex's Romance", or he was just thrown in as either a comic relief or just to make time.
Critical Dissonance: Taxi was known for having a comic style which was a far cry from Fanservice-driven shows like Three's Company or cynical, socially-relevant fare as Good Times, which was emphasized from the second season which caused ratings to drop quickly from the top 10 in 1978-79 to the bottom 10 in 1981-82 and 1982-83. However, critics certainly did not overlook the quality of the show, which earned 18 Emmy Awards (out of 31 nominations), 4 Golden Globes (out of 25 nominations) and an Humanitas Prize (the TV equivalent of the Pulitzer Prize)
Ensemble Darkhorse: Both Latka and Jim are candidates. Latka was intentionally conceived as such, but the edge goes to Jim, who originated as a one-shot character in the season 1 episode "Paper Marriage" and was reintroduced as a regular in season 2.
"Funny Aneurysm" Moment: When Latka was convincing his mother he would be better off in America, he showed her a People magazine and explained "In America, a man can become another O.J. Simpson!"
In an earlier episode, Latka's goes to fight a revolution in his homeland. Taking that his fictional country is much a spoof of Eastern European countries, it lost much of its' hilarity some twelve years later when these countries faced general unrest.
In another episode, Louie is watching TV, and the program is playing a public-domain song called Temptation Sensation, which is better known these days as the theme from It's Always Sunny in Philadelphia, which of course also stars Danny DeVito. Amusingly, both shows also have an intro sequence that consists of footage filmed from a car while a cast member drove.
Karma Houdini: Louie in "Crime and Punishment". when he confesses that he was fully responsible for Jeff selling parts and that Jeff was covering Louie, the boss believes that Louie is simply covering for Jeff, thinking that he'd go easier on Louie than Jeff, and even invites Louie to play golf with him. As Louie says at the end of the episode, "crime pays".
The Scrappy: Some of the writers apparently felt that Simka was this when she became a semi-regular in the final season (with a more abrasive personality than she had in her guest appearances). According to an interview with writer-producers Glen and Les Charles, some writers simply refused to write for Simka.
Seinfeld Is Unfunny: At the time the show began, Danny DeVito's height wasn't well-known, so the pilot was able to make a surprise joke with it when he climbs out of the cage and appears next to the other actors he'd just been ordering around.
Strawman Has a Point: In "Call Of The Mild", Elaine thinks that going to a week's retreat from civilization would be too much for a group of New York cabbies. And being trapped in a cabin in the middle of a mountain for a week without either food or electricity just before an snowstorm isn't a nice experience.
