I remember finding this years ago and laughing my head off. What a delight to find it again! I love your characterizations, how you make the Robins sound young and yet undoubtedly themselves, with Batman still being so...BATMAN while also being hilarious and prone to fatherly pride/actions. ("Did he win?")
I also really like your art, and how being able to picture the moment when all occupants of the Batmobile realize that Terry's dropped a baby-bomb, and then putting on their masks, is way funnier than it could ever be if you'd drawn it straight. Even when you only show the car, it's easy to tell what's going on.
"Tim, I didn't know you at that age." And even though this is so out of the realm of canon, it totally still works with it. <3 I'm sorry I never commented before but I'm certainly doing so now, because it's too amazing not to.
