Experienced rock climbers can achieve single-finger chin-ups. Whether or not they can do this in the rain while wearing a sodden trenchcoat, with two broken fingers, a history of alcoholism, and being chased by a homicidal replicant is another matter. Postings from rec.climbing suggest that this kind of action is as much a matter of technique as strength. A: Easily. He’s a replicant. 🙂 See section 14.
