Meet Ronnie and Donnie Galyon. They are the world's oldest conjoined twins, having just celebrated their 61st birthday. These guys lead a pretty incredible life. They're basically joined from the chest down and share just about everything south of the border. We had many questions about how these guys function on a daily basis (including Zane needing to know about how they take a dumb and use their crank). Luckily, most of our questions were answered in this video.
