Am I seeing double? Twins Separated at Birth?

Have you ever had that experience where you are absolutely sure that you keep running into or seeing the same person, only to find out that there are two people that your brain recognizes as one in the same? This happens to me quite frequently. The similarities between two people are astonishingly similar in my memory, but when shown pictures of each side by side - well, not so much.

This happened recently when I was promptly informed that a character on CSI was NOT in fact making guest appearances on CSI: Miami as I had believed. Well, you don't tell me I'm wrong unless you've got some credible facts to back it up, bucko. Off I went to imdb - the wikipedia of all things celebrity. And much to my surprise, it was true! Greg from CSI (played by Eric Szmanda) and Ryan from CSI: Miami (Jonathan Togo) are not the same person! Take a look at these photos from their imdb profiles and you be the judge!
