Meet Ronnie and Donnie, the world's oldest conjoined twins. The twins are joined from the sternum to the groin and share a set of organs. The two are celebrating their 61st birthday, which makes them the oldest conjoined twins on the planet. Free Beer, Hot Wings and Zane had many questions about how they live day to day. Who is in control of what, how do you go about taking a dump, and what does it feel like to share your nether regions with a family member? Luckily for the guys, most of those questions are answered in the video.
