[[caption-width-right:350:"I hope they throw the book at you!"]]

* 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.
-->'''Nana [[spoiler:Harley]]''': You rotten little scamps! I struggled to make a good home for you and ''this'' is the thanks I get?! (''smacks both Dee Dees in the behind with her cane'')
-->'''Dee Dee''': Ouch!
-->'''Nana [[spoiler:Harley]]''': Break a Grandmother's heart! I hope they throw the book at you!
-->'''Dee Dee''': Oh, shut up, [[spoiler: Nana Harley]].
* 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? [[ComicBook/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.
** The icing on the cake is the fact that even ''Joker'' [[ActuallyPrettyFunny cracks a smile.]]
-->'''Joker''': ''(grins in a mix of anger and amusement)'' Funny guy.
* 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.
** [[http://68.media.tumblr.com/tumblr_lrjcayLDN41r2r95ao1_1280.jpg The look on Joker's face]] when he says that last part makes it a hundred times funnier.
* While the Joker's death in the flashback was pretty dark, it was funny how his last words in the uncut version of the film were "That's not funny!"
** Made funnier (and at the same time, [[TearJerker heartbreaking]]) 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. Until [[GutPunch Tim]] shows up, of course...
** When talking about starting a family, we get this from Mr. and Mrs. J.
-->'''Joker:''' And Harley and I have been thinking that it's time to start a family. Add a Joker Jr. to our merry brood!\\
'''Harley:''' (''looking disgusted'') But rather than go through the ''[[SarcasmMode joy]]'' of childbirth, we decided to adopt!
* 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!
* Two words: [[ItMakesSenseInContext "Flag pole."]]
** Even funnier is Bonk clinging to the flag pole in fear of falling after he crashes into it.
* Terry: "Like [Bruce] said, who sleeps anymore?"
** Cut to the club. Guess what Terry's doing?
* Matt's back in full force, being a charming little [[BrattyHalfpint brat]], as always.
--> '''Matt''': (''points at Terry'') There's a stranger sitting at our table!
--> '''Terry''': (''totally deadpan'') Ha ha.
** A moment later the two are glaring at each other, when Terry flicks some of his cereal off his spoon, and straight at Matt's face.
--> '''Matt''': [[NoIndoorVoice MOM!]]
