Cool and Unusual Punishment - The two losers of each round before the final are ejected from the quiz block into something gross or dangerous, even if they're currently in another universe or era in time and the quiz block is the only way to get back.
Extreme Omnivore: Izzy displays this trait here in her appearances, despite not doing so in her own show. In her first appearance, during a game of DangerBox, she happily drank a smoothie made from fish eyes (which she apparently makes all the time at home), and swallowed a live squid whole (however she puked him up after eating oatmeal cookies). In her second appearance, she found the smell coming from a living garbage can to be delicious and ate some of his garbage.
Gainaxing - Chudd's female dinosaur disguise in "Dinosaur". Oddly, in the UK the Non-Mammal Mammaries only bounced when he jumped, which was about twice, but in NA they bounced with every movement he made.
Gasshole: One of the toon contestants is a kid known by the nickname "Burp", and for good reason. He doesn't even speak, he communicates entirely by burping, and his sister had to translate for him.
Getting Crap Past the Radar: Skatoony is one of the few shows to literally get crap past the radar. There's a whole round call "Hoo Flung Dung".
Here's an example that doesn't involve literal crap. In "Invasion", we have the Earl bathing in a bathtub full of jello. You don't want to know what got in the jello.
Lifeline - Earl's Halfway Deal. Halfway through the final round, Earl will offer to give the contestant some points in exchange for time off the clock. However, if the contestant is really good and only has 1 or 2 points to go before winning, Earl won't bother offering the deal.
Speed Round - The Skatoony Quiz Champ Challenge (the final round)
Stock Footage - The NA episodes are edited versions of the UK episodes. The side plots are the same and all that's changed is the voices, the contestants, the questions, and Tony is replaced with Charles. All singing by Earl is taken from the UK version.
