The Batkids have the same twenty dollar bill that has been going around for like 16 years straight or something - beginning with Jason and Dick
Jason, 12: I bet you $20 that I can make Bruce cry without saying a word
Jason: *walks up to Bruce and hugs with love in his eyes*
Bruce: *violently sobbing and picking Jason up*
Dick: *angrily walks by and slyly hands Jason a 20*
Dick, on a skyscraper looking down at a different one: I bet $20 that I can make this landing
(Info: this genuinely should not be possible for Plot Reasons)
Jason: okay but if you die I get to keep it
Dick: *jumps and lands it*
Jason: *sadly climbs back down to the street and hands a proud Dick the SAME $20 he earned not too long ago*
This goes on between them for years - up until you know what
Dick, out of habit: I bet you $20 you can’t do six front flips in a row
Tim, new and eager to please: watch me bitch
Tim: *does it perfectly - maybe with a tad bit of a waver but still*
Dick, crying hysterically for many reasons: *hands the faithful $20 over*
(For plot reasons Tim never spends it for X reason)
Steph: I bet you $20 I can make that guy over there ask for my number
Steph: *comes back over after successfully getting him to ask*
Tim: *handing over the 20*
Steph: oh you’re fucking on
Steph: DAMNIT *hands $20 over*
Damian: -tt- yes obviously I can. I shall take on the bet
Damian: Thomas, I will give you a 20 dollar if you can scare Father
Duke: *goes on a quest for a few days before he genuinely scares the crap out of Bruce*
Duke: GIVE ME THE $20 HOE
By now, it’s a very big inside joke between the bats
It’s Dicks turn with the $20 when it happens like the first day
Jason: hey I bet I can make Bruce cry
Dick: oh please he hasn’t since 2013
Jason: *walks up to Bruce, says a few words, hugs him tightly, walks back over to Dick*
Bruce: *wonders off and a few moments later - you hear crying*
Dick: *passes a very wrinkly and used $20*
Jason: what the hell is this? The routing number has been out of rotation for years
Dick: oh it’s the same one that we used back when we made stupid bets - it’s been around the family
Jason: *definitely not crying*
Anyway; the reason I made this post was cuz of this headcanon
The bat siblings might have a $20 bill but there’s a 75% chance they won’t give it to you because “oh it’s not spending money”
“(Bat) YOU’RE A MULTIBILLIONAIRE”
“I know but this one is special-“
