"HELLO, CLASS!" Hammer boomed happily when the class assembled in the Danger Shop. Behind him was something that looked quite similar to
this, though maybe actually with fewer handholds.
"Sometimes," Captain Hammer told them, playing with a grappling hook, "you will not be able to rely on your sheer physical power in a situation. While I, being the strongest man in several states if not the world -- I know, I know, it's hard being me and having to deal with the constant attention and adoration -- have never had to rely on many smaller gadgets like this one, many heroes do! And you might be familiar with some of them! Villians, I've noticed," he added ominously, "are very fond of using computer...y....thingies for nefarious purposes, for instance!"
"Anyway!" he said, clearing his throat and dismising all thoughts of Dr. Horrible and his little beepy devices from his brain, "today we're going to rappel up walls. You can use a harness if you want, though remember!" He pointed a finger at them. "There are no harnesses in the real world."
He thought that was Deep.
"Your goal is to get to the top if you can. You're welcome to work in pairs if you'd feel more secure, but remember! There is no buddy system in the real world!" Again with the Depth.
