I saw this freak of nature in a documentary about arm-wrestling called Pulling John (Brzenk) and was blown away.
At 6'4, ~270 pounds, he was shown performing both a human flag and one armed chins. He also claims a 380 pound ONE armed max curl and a 950 lb squat.
Aside from being a real-life Russian Drogo with super-human strength, he defeated the greatest arm wrestler of all time, won a world championship in the 2-man bobsled along with a bronze in the olympics, and is currently training for olympic judo.
Some other crazy stats:
21.5 inch biceps
18.9 inch forearms
Has anyone heard of this guy?
