Guess what! You weren't on a rooftop today! You were in the Batcave itself. But
this Danger Shop simulacrum (scroll down on the link) probably wasn't what you might expect from the Batman you knew. It was so bright.
"Hello, my fledgling justice learners," Batman said. Um. The less said about what he was this week, the better. Just go with it, okay? "This week, we're going to discuss how you put your best foot forward to find a crime."
A red rotary phone - without a rotary dial, mind you - was sitting on a table when it suddenly lit up,
glowing a bright red while screeching an alert.
Batman picked up the phone. "Yes, Commissioner? The Penguin put together an art installation in Gotham City Park with deadly umbrellas? I'll be right there!"
Batman hung up. "Don't worry, my young pupils. There is no real danger right now. That was just... a demonstration. Remember to always stay near a phone, or at least employ someone to stay near it for you. Make sure the phone can attract your attention at a moment's notice. And perhaps most importantly, mind your manners. You will be talking to the Police Commissioner, after all."
"But don't forget. You don't need to identify yourself. The Commissioner knows who he's calling. And in case a vile villain has cracked the case at the policeman's post to make a felonious phone call, you don't want to accidentally give your real name and expose your identity."
"Now, unless you have any questions, I think it's about time to see what you can do."
