The briefing to planet Kleer during the loading screen has her joking with the idea of her being put in someone else's brain if Sam dies.
During the cinematic to the second level on M'Digbo, Sam is being given a bunch of gibberish from one of the locals. Not even NETRICSA herself can decipher it.
One of the secrets in the level is... a pair of Simbas getting it out.
After successfully defending M'Keke Village from the invaders, the locals celebrate with Sam. Cue the chain of photos. The next day Sam is introduced to Klodovic, and at their first meeting, he shits on Sam's foot.
The ending to the Ursul Suburbs has Sam finding a well of wishes and throwing a coin on it, wishing to see the path to the Simba Shaman's location. Turns out it's in front of him, and there's a huge billboard on it called "Lucky's Imprisoned Shamans".
At one point, while releasing the Simba prisoners, Sam and Nettie find out a big shiny spark. Cue Nettie's reaction and Sam's snarky response:
NETRICSA:A shiny light! Maybe we should check it out!
Simba Witchdoctor:I will summon Kwongo now! [Witchdoctor beats on a drum... and completely fails to summon Kwongo.] Simba Witchdoctor: Hmmm... I'll have to try something completely different. [Witchdoctor busts out a DJ set and starts jamming out.]
The aftermath of the boss battle. What do you do with a gorilla corpse the size of a football field? Roast it on a spit.
The beginning of the first mission on Magnor has a witch stopping at a semaphore, getting drunk... And being smashed by a train which came out of nowhere.
How does the second level of Magnor begins? With an enemy being awakened... With a fart from Sam.
How does Sam summon ZumZum? By calling to Boss 'R Us and asking for an end-of-level boss!
Just the fact that the Gnaar, enemies of Sam back in TFE and TSE, are simple employees in several places and have an own news network! Quite a downgrade from TFE and TSE where they were mooks.
Sam being surrounded by Chi-Fang locals everywhere he goes. While intentionally Played for Laughs back in Magnor (seriously, outside of foreshadowing Sam having to go to Chi-Fang, what were ChiChies doing on Magnor, and especially in Branchester?), in Chi-Fang it's even more hilarious.
After the Wheel of Fortune level, everyone on Hong-Pong gathers to celebrate Prince Chan's birthday. He proceeds to eat a local and "recite" his newest poem. Sam can't get anymore of that and interrupts it. The ensuing confrontation has every local to run... Except an old man. Sam gets the baddies to agree until the local goes, which he does... At a very slow pace, with a dramatic music playing on the background. He lasts more than 20 minutes to get out.
At the end of the first level in planet Kleer, Sam enters the building only to find... A toll booth! Whose clerk (a Gnaar) refuses to let Sam in unless he pays the fee, which happens to be... 50000000 in Kleer Drahmas. (While the next expensive one is 90) Sam, seeing the large row of vehicles behind him, is forced to indulge in robbery towards the Gnaar attending the booth. The Gnaar complies. Bonus points because every people he finds during this cutscene is part of a race Sam has disposed of by millions and millions during TFE, TSE and II... Including the aforementioned Gnaar.
The opening cutscene for Count Kleerofski happens... In a circus, where countless of Kleer witness a clown kamikaze falling to the lava while the GNN broadcasts the whole thing. Then Kleerofski himself plays the magician, summoning... A flowerpot and three bunnies before growing in size for the battle. For bonus points, the music used for the cutscene is the cheerfully happy combat music used in The Great Junkyard, from Magnor.
How Sam uses the Elvian cannons, literally just lying on top of one of them and clinging to it for dear life. It's a mystery how he even fires it!
Sam winning the trust of the Elvian people in and heroically walking off to go fight Cecil the Dragon... only to trip and fall face-first into the camera, breaking it.
The Coast 2 Cost level can head to several moments of hilarity, as the AI on the jet enemies aren't the best at flying in tight spaces, which can lead to them regularly smashing into walls and exploding all on their own.
At the end of the level, Sam politely knocks the door of Kingsburg in order to see the King and gets laughed at. But that's not the funniest part. At noon, while the guards are still laughing, a ladder falls near Sam, and a woman invites him to enter. Cue NETRICSA's jealousy in the next briefing, and not speaking to Sam unless necessary until the end of the chapter:
"Why in the world did you shut me last night? HUH? I mean, you never did that before. I remember a ladder being thrown down, and a... a WOMAN! I knew it! You could've at least let me hear what she had to "say". Whatever, who am "I" to know what's going on, right? All you need to do is to find your way to the Church of Rock. And that's ALL I'm going to say."
The jealousness doesn't end here. At the briefing for the Castle of Rock level she's still mad at him:
"Well, you saved that poor girl. Plus your aim was poor. Maybe because you spent the night with that... that... morally challenged woman! Now, all you have to do is to reach the Castle Gates. Maybe you will see her again, right? Of course you will, because there is a big Wedding Ceremony behind the Castle Doors. And, of course, you are invited."
After fighting his way through Kingsburg, Sam descends into the sewers by ragdolling his way down a manhole and hitting every pipe and piece of metal grating on the way down.
After the princess was kidnapped at the end of Castle of Rock, a cutscene mimicking a detective show follows, with Sam looking at some suspicious people: the consort, the King and the Queen. We never see the Queen's face because Sam is looking at her... other assets, saying that he might have to do further... "investigation". And hoping the princess is "as good looking as her mother", hoping for a "happy ending".
The cutscene for the beginning of Floaterra has Sam skiing across the sky. At one point, he passes below a Boeing 747-like commercial airship.
NETRICSA's briefing for Floaterra has her still chastising Sam:
"Don't think I didn't see where you were looking back there in the Royal Quarters. Remember, I can see what you see, and YEAH, they are probably fake."
Doubling as a Take That!, the end of said cutscene displays the island as if they're a typical Doom's episode map. Even NETRICSA herself lampshades this:
The cutscene for the boss battle against Cecil has Sam and Cecil, face to face, about to engage in the banter you expect from a Save the Princess plot. But things take a weird turn: Sam and Cecil, upon knowing how the princess looks like, turn the battle into... A battle for who gets to die (the winner) and who gets the princess (the loser).
After freeing the natives of the different worlds that Mental trapped in Sirius's Moon, Sam tries to rally all of them with a Rousing Speech. The whole scene plays like a presidential speech... Only that the Gnaar reminds us whose side they're really on by having one unplug the audio at key parts and turning the whole speech into a cowardice speech. It still works, as plenty of ships start departing the moon.
Sam breaks into the hangar housing Hugo by setting a time bomb. Deciding that "five minutes should be enough", he sets the timer to 00:05... only to find out too late that this means five seconds.
After the Alliance fleet invades Mental's HQ planet Sirius, we see a propaganda TV broadcast:
Gnaar: The Alliance maggots have penetrated our precious shield and invaded the city. However, there is no need to panic, as our troops are well prepared. See them crush the enemy into oblivion... (the Mental troops get instantly splattered) ...uhm, we'll probably see it later.
