Sorry guys, been ages since I've posted here, so I'm not up with the FAQs. Hope this hasn't been asked too repetatively.
I notice there's a red haired man in the background of so many episodes. He usually doesn't have any lines, just swans around in the background. I've seen him in episodes as early as The Chinese Restaurant, right up to near the end. In one episode, possibly The Doodle, Kramer asks him the date on the street. I believe I also saw him as a doctor in the background of one episode. Whenever Jerry and the gang are out somewhere, this red haired man seems to pop up.
Just wondering who he is... is he a friend or relative of the cast or crew? It gets to the point where I'm looking for him in every episode now. Anyone know?
