Baby Bruce: Nightwing! I am Batman, I want you to train me.
Nightwing: Sure Batkid, but only if your hottest, most talented guardian signs a permission slip.
*Later that night*
Baby Bruce: Jason? Nightwing says you gotta sign a permission slip so he can train me.
Jason: *trying his hardest not to die again of laughter* Okay, kiddo, but only cause Nightwing asked.
Dick, meanwhile: *trying his hardest not to scream*
