 You're telling me that in order to tell your kids from each other, you've got to have the eye gunk? I am married to an identical twin. My father was literally the least observant person that ever walked the face of planet Earth. He could tell my wife and her sister apart. Do either of them have an issue with a teardrop? None at all. There's no eye gunk involved in any of this. God's honest truth is that looking at this photo, I would not be willing to bet my life on who it is. Greeny with Mike Greenberg.
