When you see Batman at the middle of the dancefloor during the annual Justice League 80’s Tribute Dance Party…

Hal: *shouting over the noise* I must say, Bruce, it’s amusing to see you thoroughly de-high-horsed.

Bruce: That isn’t a word.

Hal: Oooh, back on the saddle he climbs.

While the rest of the Justice League drink their coffee…

Batman: It’s a brain and nerve tonic, full of proteins and electromagnetic juices. *offers cup to Hal*

Green Lantern: *takes a sip* Wow! It’s like there’s a party in my mouth and everybody’s invited!

When you’re in the middle of a Justice League meeting, but you’re trying hard to remember if you’ve picked up your wife’s clothes at the dry cleaner’s…

Hal: Psst. Hey, Barry. Can I get an invite?

Barry: To what?

Hal: To the party in your head.

Break room at the Watchtower…

Hal: Clark probably has a very good sense of humor.

Barry: I’ve never heard him say anything really funny.

Hal: But it’s common sense. He’s got super strength, super speed. I’m sure he’s got super humor.
