Post-mission debriefing (and you really just want to get some sleep)…

Bruce: Questions?

Dick: Is this your only lead?

Bruce: His responses to my interrogation were hostile at best.

Tim: Clarify “hostile”.

Bruce: *through his teeth* Use my tone now as a guide.

When you’re bored during patrol and decide to get creative with Rock-Paper-Scissors…

Dick [to Tim]: What is that?

Tim: That’s fire. It beats everything.

Jason: *smashes his hand on theirs*

Jason: Oh, really? Does it beat water balloon?

Damian: -Tt- *walks away*

Outside Barbara’s apartment, planning to win her back after hearing that she’s dating Luke…

Dick: *scoffs* Funniest guy she’s ever met.

Dick [to the door]: I’m funny, right?

Dick: What do you know? You’re just a door. You just like knock-knock jokes.

Dick: *laughs heartily*

Dick [to himself]: Save it for inside!

Right before he got a taste of the infamous Dick Grayson temper…

Deathstroke: Nightwing, that’s a nice tan… But I’m surprised you get any sun at all, considering how much time you spend in Batman’s shadow.

Sometime before they became Batman and Robin…

* Watching from a kitchen window as Damian viciously cuts down animal-shaped bushes at the Manor grounds with a katana *

Dick: I’m going to climb over that anger wall of yours someday and it’s going to be glorious.

Talon, Raptor, Deathstroke, Midnighter, and Owlman having coffee together…

Midnighter: Nightwing is so hot right now he could take a crap, wrap it in tinfoil, put a couple fish hooks on it, and sell it to Ra’s al Ghul as earrings.
