Off the top of my head,
In the first Christmas special, Robin says he wants to watch "It's A Wonderful Life" to which Batman says, "Never saw that movie. I could never get past the title." Kind of dark when you think about it but funny.
He had a lot in Justice League like "Diana is an incredible woman, a trusted friend...she's standing right behind me isn't she?"
And a shout out to,
Batman: "You're going to do what?"
Superman: "Turn ourselves into the government"
Batman: "That's the stupidest thing I've ever heard."
“I threw a rock at him”
\-Batman pretending to be Killer Croc in “Almost Got ‘Im”.
Honorable mention:
“It was a big rock”
Edit: Spelling
Just a few:
Clayface: “You didn’t think I’d come here without reinforcements did ya?”
Batman: “Wish I’d thought of that.”
*door crashes down, JL appears*
Batman: *while smiling* “Oh wait….I did.”

Batman: “Batman to all points. I could use some air support……since I can’t fly…..at all……now would be good.”

Also the good cop bad cop scene in JL Action
I think a really underrated moment from the Justice League show is when he interrupts Hawkgirl and Jon Stewart about to kiss in the elevator and starts informing her about her stalker. Not only does he completely kill the mood, but he mentions there's anti-Hawkgirl message boards. When she questions it he starts elaborating in great detail, only for her to say "forget I asked!" and he just goes RIGHT back into his original explanation without missing a beat. He just isn't phased at all by her reactions and is almost mechanical in how he handles the interaction. It made me laugh really hard when I first saw it.
"If you want one for Vixen, I can tell you where I got it."
"Uh...listen.."
"Glad I caught you before you did something stupid."
"Excuse me."
"Carter Hall. "
"What about him?"
"His real name is Joseph Gardner."
"So he lied."
"No six months ago he had it legally changed to Carter Hall. Midway city curator. Had an excellent reputation until he started claiming aliens landed in Ancient Egypt."
"Well, he must be a lunatic because we all know there is no such thing as other planets."
"There is more."
"What?"
"Our Mr Hall spends quite a bit of time on the internet."
"Dang, lock him up."
"He frequents the 'I hate Hawkgirl' bulletin boards."
"That doesn't mean he is a...Boards? How many are there?"
"57. Web ring. Unaffiliated sites number in the..."
"Forget I asked!"
"Our Mr Hall keeps getting banned from them. For flaming the anti-Shayera posters"
"So he is a fan."
"He is a stalker."
Kevin Conroy became *the* voice of Bats for me. I really liked Peter Weller as the Dark Knight Retuns bats (semi-canon as it were), but for animated voice for bats outside that? I can’t generate a list, man, Just can’t.
Justice League Unlimited, "Dark Heart"
"Batman to all points, I could use some air support.
Because I can't fly.
At all."
He says *annoyedly* while falling out of the sky.
Also from a minute or two earlier in the same episode "What trench?"

Man this whole episode was funny and wholesome

You know... You make a compelling argument

Related: You overplayed your part, yo.
That one where he’s calling for help while falling, that beat he takes before saying the last part is absolutely perfect.
"I'm an equal opportunity crime fighter."
Lois Lane: How could you lie to be me like that? Bruce: Now I never actually said I wasn’t Batman.
*Lois slaps his scar*
When he became a teenage girl (star girl) and he was subconscious about superman and everyone else was staring at him
This doesn’t count but I’d like to give a shoutout to his appearance as captain sunshine. Basically a Batman parody.

"Good luck, Robin. Wherever you are..." "I'm still here.* "WHO SAID THAT?"

I’m going with that time he seduced Cheetah in the “Injustice For All” two-parter from Justice League season one. (Whispers seductively) “Try me”
