Bruce "Brooding Bat" Wayne is a very, very serious man. As much as he's hard to get along with, sometimes, everyone in the JLA begrudgingly respects him. How can they not? He's their resident tactician and has (grown) children who still look to him for support/advice/guidance (sometimes).
He's a very serious man indeed. Unless a harmless otherworldly creature they've captured for research suddenly gets out of its cage while he's gone from the Watchtower and the other JLA members have to wrangle it back. Took them a humourously long time, too. They don't notice it when he comes back, but you know who does? His long-time friend, Oliver Queen.
Oliver sees that barely-there smirk lifting the Bat's lips, he can feel that amusement from Bruce Wayne. They exchange glances, but Batman shrugs it off and “tightens” the security measures for the creature.
Oliver remembers just how different of a person Bruce was when they were younger—especially during their high school days.
Ollie, snickering: "This prank's going to be sick!"
Harvey: "Don't you think we're going a little too far?"
Lex, holding clown masks: "Nonsense! Now where's Bruce? Did he get caught already?"
Bruce, carrying a gallon full of red liquid: "I'm here!"
Ollie: "Holy shit! Where'd you get that much fake blood??"
Bruce: "....."
Bruce: ".... You wanted fake blood?"
Harvey: "BRUCE?!"
Ollie: "....I think I hear my bodyguard calling for me."
Lex: Already slinking away.
(It was indeed fake blood, Bruce just enjoyed seeing them go pale)

Bruce: "Thanks for handcuffing Lex to the table guys."
Harvey: "You're....welcome?"
Ollie, shrugging: "It was easy."
Lex: "....MFER- MY EYEBROWS ARE GONE!"
Bruce: "YOU NEVER HAD EYEBROWS!?!"
Lex: "YEAH, BECAUSE YOU TOOK THEM????"
Bruce, pulling out two wax strips: "WELL HOW WAS I SUPPOSED TO KNOW THESE WERE FAKE?!??!?"

Bruce, on Ollie's phone mimicking his voice: "AHÆHÆHÆHÆ byeeeee!!"
Ollie, driving: Cringing "I don't laugh like that!"
Bruce: "Yeah you do! You go AHÆHÆHÆ"
Ollie, scoffing: "No, I do not!"
Bruce, rolling his eyes: "That time Mr. Harrison slipped on a wet spot in the restrooms."
Ollie: "HAHÆHÆHÆHÆHÆ-"
Bruce:
Ollie: "...."
Ollie: "Damn."

Harvey, arriving completely dishevelled and sweaty: "hy-"
Bruce: "You missed first and second period."
Harvey: "i knw-"
Bruce: "And you're all messy!"
Harvey: "I know!"
Bruce: "And that shirt is not a good look on you."
Harvey: "...."

Bruce, arriving at school with a shaved head: distraught.
Harvey: ".....yikes."
Ollie: "Oof-"
Bruce: "Alfred said my hair was too long and needed a “fresh” cut 😭"
Ollie: "Are you sure he doesn't just hate you?"
Harvey: "Ollie!"
Ollie: "What??"
Lex, patting Bruce's back: "Aawww don't worry Brucie. I think you look great in your new cut!"
Bruce, tearing up: "Of course you do!" Cries.
Lex: "...."
—————
Harvey: "Hey Brucie... I know you said you wanted to take Alyssa to the dance, but... She came up to me and, well..."
Bruce: "Oh, well that's fine. Nothing we can do about that I guess."
Harvey: "Really?? God- sometimes I forget how nice you can be. If I were you I'd have punched me in the face."
Bruce: punches Harvey in the face.
Harvey: "OW?! Bruce?!"
Bruce: "What?"
—————
Ollie, storming down the hallway: "I can't believe you just did that??"
Bruce, following behind Ollie: "Hey, listen, I warned you this would happen- now could you slow down?! I'm thirsty!"
Ollie, shocked asf and turns around to face him: "Excuse me?!"
Bruce, buying a drink from the vending machine: "You're excused."
Ollie: "You're unbelievable!"
Bruce: "I know."
Ollie, huffing: takes the drink from Bruce before he could drink from it.
Bruce: "Hey! I was going to drink that!"
Ollie, licking all around the neck and lid of the can: "Here."
Bruce, taking the drink back: "Thanks." Drinks.
Ollie: "...."
Ollie: "You're sick. You're a sick, sick person!"
Bruce: "You're just now figuring that out?"
