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.
Acceptable Political Targets: The slobbish father, Lance Prevert, is a Senator. Specifically, a Canadian Senator note Unelected, appointed for life, notoriously prone to chronic absenteeism, and even more notoriously just a rubber stamp on nearly all government actions — Canadians frequently have serious debates about either eliminating the senate, or reforming it radically. (an even more acceptable target). Originally, the writers wanted Lance Prevert to be a prime minister, but they thought American audiences wouldn't get it, so they made him a Senator since U.S. and Canadian Senators have more in common than people may think.
In a real life instance of this trope, Les Lye revealed in an interview that he was nervous about the implications of a sketch featuring German dungeonkeeper Nasti tormenting Kevin Kubusheskie, who is of Polish descent.
A lot of the jokes on the episode "Adoption," where adopted children are treated as little more than pets (Dougie is adopted by the Preverts because it cost less than buying a dog) and slave labor (the infamous scene of Lance Prevert calling the adoption agency and calling them "Damn bureaucrats!" when they tell him that they can't take Adam back because adopting a kid is not the same as hiring a housekeeper for the day, though considering that Lance forced Adam to work and won't feed him, the adoption agency should have taken him back for neglect). While it is funny in a sick way, watching it now compared to as a kid, you can see why Nickelodeon in America didn't want to air it. Even the writers and show creator thought the episode was in bad taste.
Ear Worm: The opening theme, a Dixieland rendition of the William Tell overture.
Germans Love David Hasselhoff: While the show was a success in Canada, it was a cultural phenomenon when it hit the United States of America and the green slime on the show became associated with Nickelodeon.
Harsher in Hindsight: George Bush Shoots The Wrong Quail, from "Mistakes," comes off a bit more harshly in retrospect after George W. Bush's Vice President, Dick Cheney, did aim at the wrong target during a quail hunt and consequently shot a friend in the face.
That scream in opening theme song sounds an awful lot like the scream that cost Howard Dean the Democratic primaries in the 2004 Presidential election.
Les Lye's Senator Lance Prevert is a lot funnier when you realize he's more or less like Canadian mayor Rob Ford.
Seinfeld Is Unfunny: Modern day viewers who are accustomed to more recent kid-focused sketch shows like successor series All That may have a hard time appreciating how revolutionary YCDTOTV was in the 80's.
