* The final scene where the Dee Dee sisters get bailed out of prison and bottom-smacked with a cane by their Grandma [[spoiler: Harley Quinn]] definitely counts.
* The infamous scene in the car after seeing the Joker for the first time:
-->'''Terry''': So, the Joker? [[PrettySpryForADeadGuy Pretty spry for a guy who's gotta be, what? Mid-eighties?]] Any theories on that? Clone? Robot? [[CaptainAmerica Suspended animation due to floating around frozen in a block of ice?]]
-->'''Bruce''': Shut up and drive.
-->'''Terry''': Yes, sir.
* While fighting the Joker, Terry surprises him with a good ol' [[GroinAttack knee to the]] [[UnusualEuphemism joy buzzer]].
--> '''Joker''': What are you doing?\\
'''Terry''': Fighting dirty.\\
'''Joker''': The ''real'' Batman would never-- *gets a knee to the groin again* \\
'''Terry''': Told ya you didn't know me.
* Perhaps a little on the dark side, but it was Hamill's performance that sold it.
-->'''Joker''': Dee Dee?
-->'''Dee and Dee''': We're with you!
-->'''Joker''': Boys?
-->'''The other Jokerz''': We're with you!
-->'''Joker''': Bonk?... oh right. Dead.
* While the Joker's death in the beginning was pretty dark, it was funny how his last words in the uncut version of the film were "That's not funny!"
** Made funnier when you remember [[spoiler: the Joker's last words in VideoGame/BatmanArkhamCity.]]
* "Sweetie, get mommy's bazooka!"
* When Batman finds Harley Quinn and the Joker, the latter makes a warm greeting, and they both act as if they were on a TV sitcom. HilarityEnsues.
* Given that the following line is spoken by the Joker, it doesn't surprise that it manages to be both a CMOF and terrifying:
-->'''Joker''': It would be funny if it wasn't so pathetic.''({{Beat}})'' Oh, what the heck, I'll laugh anyway! ''(EvilLaugh)''
** Makes it even more sweeter when in the future Terry, albeit unknowingly, says a rephrase of the line when fighting Joker.
-->'''Terry''': You make me laugh, but only because I think you're kind of pathetic. ''(laughs mockingly)''
** Also:
-->'''Joker''': [[CrossesTheLineTwice If you don't like the movie I've got slides!]]
* One that got cut from film but can be found in the script is when the Jokerz are trying to get away when it's obvious the Joker is beaten--only to run smack into the police.
--> '''Police''': This is the police, put your hands up and surrender.\\
'''Woof''': (The spliced up Jokerz who's done nothing but growl and laugh through the whole film): Aww, man!
* [[TwoWordsObviousTrope Two words:]] [[ItMakesSenseInContext "Flag pole."]]
