Back in the day, Batman and Robin climbed the shit out of buildings. Just a nice piece of rope between their thighs, relying upon the closeness of one another to ensure they climbed successfully. The gentle touch of Batman upon the small of Robin’s back. Whispering: we can make it. Woah! What happened. Anyways. They loved the shit out of climbing, and here in one place is every cameo from their climbing.
