All Just a Dream: to the relief of the chef, most of the Pain Inflicting Porridge episode was this.
April Fools' Day: The name of the episode, Tenacious Tacos, is enough to arouse suspicion.
Awesome, but Impractical: Most of the preparation methods look utterly cool, but sometimes are probably counter-productive. Any recipe involving eggs will have the eggs thrown about and broken before they're needed in the recipe, and a myriad foodstuffs get smashed and destroyed.
Ax-Crazy: Probably the world's first media about cooking to use this trope.
Even more so now: During the Lethal Lasagne episode, the chef uses a freaking axe to chop onions with!
He also succeeds at chopping the cutting board in half.
Badass Beard: Even more badass with mayo smeared all over it.
Eye Scream: Niclas shoves lemons into his eyes during the Superior Smörgåscake episode.
He also squeezes lemon juice into his eyes in Catastrophic Crayfish.
And rubs onions under his eyes in the Meatball Massacre.
The very end of the Christmas episode has the chef in the process of removing another guy's eyeball with a spoon, which is seen again (and again) in the April Fool's episode.
Finns with Fearsome Forests: One appears in the Sticky Cake episode. Niclas doesn't know what to make of him, and even the video description isn't sure.
Gainax Ending: "Supreme Swedish Pilsner-Sausage" ends with one of the Swedes saying "next time" before having his head spin around and distort while he screams. The screen then informs us "he died".
A Glass in the Hand: Whenever something needs juicing, squeezing or mashing, it stands a fair chance of getting crushed to death in one hand and the contents sprayed everywhere.
Gratuitious Korean: "Sidepork Pandemonium" features the cook karate chop butter in half, indicated by a Korean flag in the top right corner and subtitles (in Korean).
Heroic BSOD: Niclas is seen crying at the end of 'Massive Meatloaf Mayhem', having realized they forgot to buy mayo.
"Next time, we won't forgot mayonnaise."
In Killer Kalops, when Niclas is taking out the mayo from the fridge in order to have some pre-dinner mayonnaise, Mr. Fox trips him over from beneath the table, spilling the mayonnaise all over the floor. Predictably, Niclas is devastated by this turn of events.
Kubrick Stare: Niclas performs a sustained one during the intermission of "Carnivorous Christmas Table."
Lad-ette: In Cookie Cataclysm, one is being served. Even the chef has to quickly run away in fear.
It's a shoutout to an old Something Awful creepypasta/ARG that concerned numerically-named videos displaying bizarre black-and-white videos, purported to have been broadcast to a tiny Colorado town in the nineties.
