- Up And Atom: At the end of the story, Atom is talking to Batman and Wonder Woman when Batman disappears between shots. Atom at first thinks he's accidentally shrunk Batman, but Wonder Woman casually remarks that this is just something Batman does.
- Good Cop Bat Cop: Deadshot's interrogation. Superman wants to try being the bad cop for once in the Good Cop/Bad Cop routine they usually use, but he's such a Nice Guy that the end result is Adorkable rather than intimidating—Deadshot doesn't buy it. On the other hand, the notion of a friendly Batman messes with Deadshot so much (he can't even recognize that Bats is smiling) that he confesses out of a combination of confusion, anxiety, and general distress with the situation.
- His reaction to Batman's smile seems to imply that Batman just isn't very good at smiling.
- Beep Beep: Basically Lobo as Wil E Coyote and Flash as Road Runner.
- And at least twice, Lobo being beaten up by alien cacti.
- It's A Trap!: Basically a huge Take That! to Batman v Superman: Dawn of Justice.
Superman: You made...a Bat?!...You just stuck a piece of kryptonite into a stick?
- The reveal of Lex's greatest 'Anti-Superman Weapon'; A bat with kryptonite lodged in it....wait, what?
- And then Superman actually outwits Lex with an equally over complicated plan. "Know Thy Enemy" indeed.
- Superman pointing out that he twigged onto this being a trap because the name Lex Luthor chose for the hostage, Brie Gruyère, was simply the names of two types of cheese. You know, the stuff you bait a mousetrap with.
- Lasso of Lies: Wonder Woman tries to use her lasso of truth on Deadshot... except it's actually Plastic Man.Plastic Man: I'm so sorry, and please don't kill me.
- Then once Booster Gold enters with the real lasso, she uses it on him... and he says lots of amusing things.
- Once Deadshot sees it actually works, he gives up the name of his employer... and assumes he'll be getting ice cream with the heroes.
- Booster Gold's nickname for Wonder Woman is evidently "Wo Wo," much to her annoyance.
- Deadshot, a highly skilled but mortal assassin, spends the entire fight with Wonder Woman, a superpowered Amazon, flirting with her, evidently just to get her heckles up. The moment she pulls out the lasso, he takes off running.
- Quality Time: The episode starts with a huge melee between the League and a collection of supervillains. The Leaguers consider the fight pretty much as good as done, and start making plans for a social get-together even while fighting the bad guys. Of note, Batman's idea of a good time is to have everyone hang out at the Bat Cave while Alfred serves sandwiches, Wonder Woman's response implies that nobody else agrees with him.
- Cut to the Justice League bowling (in costume, natch). Superman makes an overly cautious approach before releasing the ball with as little pressure as he can manage, where he ends up putting holes in at least three walls.
- Selfie Help: Space Cabbie informs Batman that his fare is $38,000... or one selfie. Batman replies that he's going to go get his wallet.
- The whole episode is his various attempts to get selfies with the Justice League. About half of them have Booster Gold photo-bombing so the product he's pitching makes it in all of the photos.
- Special Delivery: Booster Gold is trying to help deliver a baby in the back of Space Cabbie's cab, while being pursued by Granny Goodness. Granny ends up taking over when she finds out what's going on.
- Mint Condition: A fight between the League and Toyman gets derailed when Toyman and Cyborg start geeking out about action figures.Stargirl: So, do we arrest him now?
Batman: I'm just gonna leave and pretend this never happened.
- True Colors: Firestorm is sent in to help Superman beat Metallo by transmuting his green Kryptonite core into lead. Instead, he runs through the gamut of Kryptonite colors: pissing Supes off with red, wiping his memories with gold, splitting him into two with black, and turning Superman into a woman with pink before getting the formula correct.
- When exposed to the gold kryptonite, Superman takes a blow to the head and demands to know why this guy's hitting him. He's not saying it out of fear or shock, but rather pure indignance.
- And then Firestorm messages Batman about the events after Superman told him not to report it.
- "Missing the Mark", from start to end, featuring the Joker (Mark Hamill) and Trickster (Mark Hamill) kidnapping famous actor Mark Hamill (Mark Hamill), Hamill pits the two humorous hooligans against each other by doing their voices, until they get caught by Swamp Thing (go ahead, guess!). It's Talking to Himself taken to a very meta extreme.
- This fantastic joke from the Trickster (note that the Trickster is introduced with the caption "2nd-rate villain")The Trickster: You're my favorite actor! I loved you in that 70s classic, about a young lad who fights impossible odds to fulfill his destiny...what was that called? Oh yeah.... Corvette Summer!
- Swamp Thing's explanation that Mark Hamill was not only a famous actor, but also a skilled voice actor, comes off as hilariously self-promoting given who is voicing him. Which is immediately undercut by Joker.
- This fantastic joke from the Trickster (note that the Trickster is introduced with the caption "2nd-rate villain")
- Clown Party: At the very end, the kids at the party demand for balloon animals. Shazam obliges and starts making them... using Joker as the source of helium.

- Wonder Woman uses her Lasso of Truth on the villain of "Power Outage" and tells him to tell her everything he knows. He says he won't...and then suddenly starts spilling the beans with glowing eyes.

- GA later shows up at the Hall of Justice still dripping wet.
- After Booster Gold comes to from being beaten by the Uthul-possessed Batman, the first thing he does is notice how different things were with his other fights. He only realizes he did better. And completely misses the still bound Wonder Woman.

Episode 5: Follow the Space Cabbie
- When Lobo offers to "split" the bounty for Mr. Mind's capture with Superman and Hawkman, he cautiously steps back just as Mr. Mind is crawling towards him — leading to multiple direct shots, from different angles, of Mind screaming in terror and getting messily squished under the Main Man's heel. Even better, since Lobo gives Superman the hind end as a parting shot and escapes with the head goop, Mind is able to harmlessly regenerate in League custody.Lobo: Ew! 'Got some Mind on me!
- Space Cabbie trying to distract Mister Mind with a photo op...with pictures of various people he's had.
- Mr. Mind's deadpan "I hate all of you" after he finds out he regenerated in prison.
Episode 6: Nuclear Family Values
- Seeing Firestorm get blasted by Sis of the Nuclear Family. The hilarity of it? She looks like the 'pretty girl in the poodle skirt' from a 1950s sitcom. Heck, ALL of the Nuclear Family looks and acts like a character from one.
- Superman and Wonder Woman being impressed by Firestorm and even saying that Batman got impressed. An excited Firestorm turns to see...Batman giving him an 'Eh' handsign.
- Dad insisting on calling Firestorm 'Sparky', much to his chagrin. His flat 'uh no' when asked if it was okay sells it since the android just keeps on doing it even when he's going to beat him up.
- How Firestorm ultimately defeats the Nuclear Family is chuckleworthy. How does he do it? Same way everything gets defused in a sitcom: a big ol' hug.
Episode 7: Zombie King
- Just the fact that SOLOMON GRUNDY is the mastermind of a grand scheme all while having to talk in Hulk Speak.
Episode 8: Galaxy Jest
- Joker's cringeworthy jokes can be funny mostly from the reactions he's getting.
- Joker's disgusted reaction to having to cheer for Superman. Just the face he makes after saying "Go Superman" is chuckle worthy.

- This scene:Joker: I know we had our differences, but I'm avaliable for the Justice League holiday part- (thrown face first into the police van by Wonder Woman)

- After he does get up to the roof, he does his famous "I. am. Batman!" line (complete with lightning behind him). Blue Beetle wastes no time joking about how cheesy it is, and Batman is visibly embarrassed.

- AND Beetle asks Khadji Dah/Scarab if he took a picture, which he says is cool with the dynamic pose.

Episode 10: Under a Red Sun
- The fact that Superman, Big Barda and BATMAN are keeping score of how many henchmen they are defeating. You'd expect this kind of thing from the sidekicks, but not the big leagues.
- How does Superman beat Steppenwolf? He tosses a broken piece of tech into the water that electrocutes him...just a minute after he brags that he'll kill Superman.
- It's worth noting that, despite beating Steppenwolf, Superman doesn't come out unscathed; notably, he ends up breaking his leg during the battle. However, once everything is said and done, he seems more amused by this than anything else, even responding with a cheerful "it really does" when Batman asks if it hurts.
Episode 11: Play Date
- Cyborg got sucked into an online match with Blue Beetle, thus missing Toyman's assault on the Watchtower.Cyborg: I've only been playing— (checks his watch) Wooo... that long.

- Cyborg giving his protest of Toyman taking Superman and him forced to have BatmanCyborg: Oh come on! Batman doesn't have any superpowers! (Batman gives him a slightly offended Death Glare)...Not that he needs any.
- Cyborg then proceeds to spam the I'm Batman taunt, much to Batman's annoyance.
- Superman's reaction to Batman carrying a Kryptonite ring.Superman: (with a black eye) You just...carry that with you?

- One of Superman's moves ends up involving him pulling off his S-Shield and using it to wrap up Batman.Cyborg: Superman can't do that!
- While Superman and Batman are annoyed with their intros, Wonder Woman...actually kind of likes her intro line for the game.

- During the fight with Repulse, Wonder Woman ends up tied up with her own Lasso of Truth, leading to a funny exchange when Hawkman asks her if she is okay.
- Hawkman being rather...awkward with seeing Superman and Wonder Woman flirting. Given he's one of the few married heroes in the comics, this is doubly funnyHawkman: Super PDA is really awkward...
- Lex Luthor getting a lot of funny lines. Yes it's James Wood, but still.
- One that comes to mind is him wanting to make billions on a vacuum based on a black hole and him telling Superman that he has delicate skin, being a red head and all (despite being bald).note
- The Running Gag involving a garlic risotto making Superman's breath smell bad. It usually goes with the Almost Kiss gag.
Episode 13: Trick or Threat

- Constantine getting a piece of rock candy...and it comes with a Peanuts shout out.
- Zatanna having to wear braces when she was a kid. Two reasons: One, somehow Klarion knew this and put them on her. And second, the fact that Zatanna, the witch with the backwards spells, needed braces at some point.

- "I can't believe Batman said 'bejeebers'."Batman: I never said that.Zatanna: You totally did.

- Adding to that...we get SUBTITLES for her spells now.
- Etrigan giving ice cream to Zatanna and Batman. Thank you for this, Cartoon Network.
- For reference, Batman at first declined, saying he's got bigger things to deal with. Then the Batmobile falls apart. His reaction? "Chocolate".

Faust: Why did it have to be rabbits?
- Said bunnies are also what stop Faust from escaping!
- Etrigan asking Batman if he wants him as a sidekick. The idea alone is actually kinda funny.
- Zatanna's fight scene with a younger Felix Faust is full of snarky comments from Faust and her using various magician-themed weapons.
- Special mention goes to when Zatanna manages to dive into her hat, causing Felix to look into it confusedly before getting a seriously nasty uppercut from the resourceful sorceress superhero as she launches back out of it.
- Merlin's deadpan delivery towards Etrigan calling for his aid.
Episode 16: Luthor in Paradise
- From the trailer, we are seeing the context of Hippolyta's question about Superman and Batman...plus it's even more funny than before since they arrived and saved Diana. They still share a 'Did she REALLY say that' look to each other.Wonder Woman: These men are my... sidekicks.
- Batman calling the Themyscerian Amazons "Prickly". Seems he's had experience with them...
- Luthor getting giddy over having hair... Before pissing Circe off.
- When Circe also absorbs Zeus' powers, she too gains a golden glowing aura like Lex... and the same long white beard which she quickly removes with her magic.

- The very concept of the Red Lanterns showing up at the Watchtower, smashing the security camera... and then waiting patiently until someone comes to answer the door.
- Bleez screaming "AMBUSH!" when the Watchtower door opens, much to the obvious confusion of Superman, Wonder Woman, and Batman.
- This is immediately followed by Bleez trying to blast Superman, only for Wonder Woman to reflect the blast right back at the lanterns. Atrocitus casually leans to one side to let Zox take the full hit.
