Gothamist has the thrilling footage of a young man in Dumbo who just hops onto his slim third-floor ledge, seemingly barefoot, to polish the outside of a window with an alarming amount of confidence and no harness of any kind. Do you know this (Spider-)man? Is he a heavy user of bath salts? Does he work at the circus as a tightrope walker? Does he suffer from obsessive compulsive disorder with regards to the smudginess of his windows? Please tell him to be careful.
